The Best Years of Your Death - S1-E3
Plot hole: In the chapel, you can see the heads of those who tried to cross Harriet (the mad matron) preserved in formaldehyde. How did she get hold of so much of it? Wouldn't her husband or the headmaster be suspicious?
Enter Batgirl, Exit Penguin - S3-E1
Plot hole: When he abducts Alfred, believing him to be a minister, Penguin suffers a peculiar memory lapse. He's encountered Alfred twice before in previous episodes, even kidnapped him once before (knowing full well that he was Bruce Wayne's butler). Yet here, he fails to recognize Alfred at all. (00:12:30)
Plot hole: When Jim's bank calls his office, Kevin is there and ends up pretending to be Jim. The Banker automatically assumes that he is not in Puerto Rico only from asking his address and social security number. It would have been very plausible for him to have forwarded the number to his cell phone, where the same scenario could conceivably occur (since The Banker refused to listen when Kevin tried to correct her).
Plot hole: When Katty is first discussing the dead girl from the plane crash who had brains in her stomach, she says the girl's flesh indicated she died months before she ever got on the plane. But then later in the episode, Katty says the plane crash girl was at the boat party (massacre) the day before she got on the plane. Everyone at the boat party was alive before dying and turning into a zombie, so the girl's flesh would not indicate she was dead for months since she only died the day before.
Time Machine - S1-E5
Plot hole: After Al guests knocked out by the Russian dancer, he is woken up by his friends. However, according to the series events before this, Terri Garr should have found him first.
Gold Fever - S2-E2
Plot hole: Roscoe and Enos are chasing the boys. They are well ahead of the Sheriff and go up into a semi with a conveniently made ramp to lose the cops. The dust was dissipated enough that Roscoe, coming up from the rear, could have seen the General in the trailer. Roscoe couldn't be that blind. Plus the trucker couldn't miss the movements of the truck settling down from the sudden adding of two tons.
Plot hole: In Blakey's office Stan shows Blakey the toy bus he has just brought for his nephew. How can Stan have a nephew when he isn't married and his only sibling is his sister Olive, who doesn't have any children?
Plot hole: When Beverly is killed the killer shuts off the main power switch which would have turned all the lights off in the house, not just those in the bathroom. (01:31:00)
The Aptitude Test / Oskar Gets a Job - S3-E9
Plot hole: Mr. Simmons asked that each student put their name on the test folders, but the folders already had names on them when he handed them out.
Plot hole: If Andy really did enlist into the Army Reserves and "forgot about it" like he claimed a warrant for his arrest for desertion would have been issued, which the police would have seen when he was arrested for pot possession in the episode "Lude Awakening." After seeing the warrant, the police would have called the Army, and he would have been returned to military control to face desertion charges. He would not have been released and sent a letter a few weeks later simply telling him to report for duty or face military prison; the option to report for duty would have no longer been available when he was gone long enough to get put in deserter status.
Plot hole: It is revealed that Malia has been living as a coyote for eight years but earlier in the season it's shown that all shape shifters lose their powers and becomes human during a lunar eclipse, which happened in the midseason finale. So why didn't Malia turn back?
Plot hole: Gracey loses the Dean while she's sleeping, but Ms Loon is revealed later to have taken the Dean, so how did she get into the room?
'Unmei no sentaku' mitaina - S1-E6
Plot hole: Akito's attack is point blank, on a ship part of a fleet with Distortion Field activated (basically, they have shields, like the good guys' robots). The explosion he causes is according to Ruri's damage report big enough that it managed to vaporize 80% of the ships they were facing, but his Aestivalis and the other 3 right floating nearby make out of it literally without a scratch. (00:05:10)
Independent Dependents - S1-E7
Plot hole: When Helen goes into the air ducts, she simply removes the grates. They would not be loose like that, they would be firmly attached. When the team enters the basement they go through an ordinary door by picking an ordinary lock. A very high security installation like Axe Industries would not have such an insecure entry, even into the basement.
Plot hole: In the pilot episode Chuck mentions his mother speaking as though she is still alive and he knew her but in later seasons it is reveled that she supposedly died while giving birth to Chuck and he never knew her.
Mac is a Serial Killer - S3-E10
Plot hole: Early in the episode, it is mentioned that the serial killer is murdering "Young, attractive blondes", yet at the end of the episode, when the gang finds all the severed heads in the killer's refrigerator, almost none of them are blonde or young, contradicting what had been previously established.
Plot hole: Dumb Donald chooses not to play hookey with the rest of the gang. He instead goes to school. The gang is even worried Dumb Donald may, "Rat them out" to the school. Yet throughout the episode, Dumb Donald appears/disappears with the gang as they are skipping school.
Home Again - S2-E9
Plot hole: Old Ash travels back in time to 1982 to snatch the Necronomicon before Young Ash ever finds it (which should, presumably, erase all of the evil events from the original Evil Dead film right up to the present). Upon escaping the cabin, Old Ash finds that the timeline has self-corrected, and his amputated right hand has reappeared on his arm. But he is still in the 1980s. If the timeline had truly self-corrected, then Old Ash's car, his friends, and he himself would have vanished instantly from the 1980s, because the purpose of their mission never existed.
Suggested correction: Time travel is not real. The rules of it are dependent on what the writers deem fit. Ergo, this isn't a plot-hole.
By that rationale, plot holes don't exist in any films, because the screenwriters are making all the rules. But, of course, plot holes do exist because screenwriters forget their own rules. In this case, the screenwriters chose to go down the path of correcting the Evil Dead timeline, but then they forgot to correct the timeline.
Baal was messing with time.
Jiu-Jitsu, Bubble Wrap, and Yoo-Hoo - S1-E17
Plot hole: Near the start we see Sheldon using physics to try and take down Tam. This completely goes against all of Sheldon's phobias about touching people, especially socks. Even before this episode he has shown his displeasure at the thought of touching people. (00:05:00)
Suggested correction: Not everyone at the boat party was "alive", there were some zombies there as well, Blaine included, it is entirely possible that she was a zombie before the boat party happened.
ctown28 ★
Which episode(s) mention Blaine and others were zombies before the boat party massacre? Everything in the show makes it seem like it was the combination of tainted Utopium and Max Ranger energy drink that night which caused the zombie outbreak, including Blaine's transformation. And the Fillmore-Graves outbreak was a separate incident that Blaine wasn't a part of.
Bishop73
Yeah, the boat party was ground zero for the outbreak, Blaine and everyone else was human when they got on the boat. Nothing suggests otherwise.

When get turned in to a zombie your flesh is dying so her flesh could be dead.
Suggested correction: I think you're assuming that when zombies die for real they decay at a regular rate, but we've only seen frozen dead zombies - so maybe a dead zombie's decayed flesh decays even faster?
