Corrected entry: It makes no sense why the Gecko brothers took the bank teller hostage at the beginning. Their plan was to get across the border into Mexico and to the rendezvous using the Fuller family, and their RV was perfect. But what was their original plan? Were they gonna have the hostage drive their car while they hid in the trunk? She would have given them up immediately. Also let's not forget that her face was on TV news programs which makes her a liability at the border gate. Basically there is no logical reason and all they would have done (if Richie didn't kill her) was create unneeded collateral.
Corrected entry: When Sex Machine is turning into a vampire, he hears a voice in his head saying "Kill them. Kill them." This is most likely a homage to the original Friday the 13th film where the killer Mrs Voorhees hears similar voices saying "Kill mom. Kill mom." Tom Savini who played Sex Machine did the special effects for that film.
Corrected entry: After Jacob gets bitten, he estimates that it will take him approximately half an hour before he turns into a vampire. What does he base his plot-convenient estimation on? Most of whom were bitten became vampires within minutes. It has been argued that this may be a result from him being a priest. Even if that's the case, with no prior knowledge on vampirism Jacob has no reason at all to think that his faith will slow down the process of turning into a bloodsucker.
Corrected entry: During the motel scene, Seth comes back in with bags of food and gives some to Richie, before asking where the woman hostage was. We see Richie chewing, then a split second later (shot is from behind), we can see Richie pick up a beer bottle and take a sip, but the very next shot (front view now), Richie is still chewing and holding the burger with two hands, and the beer bottle is not even visible.
Corrected entry: When the war veteran is telling his Vietnam story to the remaining survivors, Sex Machine grabs him from behind and bites into his neck. Although if you look at the way everyone is standing there is NO WAY that he could get behind him without being seen by Seth, Jacob, Kate or Scott. (01:22:15)
Corrected entry: Considering how many hundreds of bats were trying to bust into the bar, there's an awful lot of empty space to move around in and turn your back on. Since the vampires' human forms are bigger than the bats and the swarm of bats filled the hall nicely, that bar ought to be packed wall to wall. (01:23:20 - 01:30:45)
Corrected entry: In the opening shoot out in the liquor store, Quentin Tarrantio shoots bottles of liquor, that then pour onto the clerk. George Clooney then throws a flaming roll of toilet paper at the clerk, causing the liquor to burst into flames. This is a neat idea, but only liquor that is 100 proof or higher(very high alcohol content) will burn. The bottles shown breaking are normal booze, which is mostly 40-80 proof and not very flammable. All of these bottles would have had to be Everclear or Bacardi 151 or a similar high alcohol liquor to cause a fire like that. (00:08:00)
Corrected entry: When all the vampires get hit by the sunbeams they explode, with no fire. But when Carlos frees them and the sun shines in all vampires explode into a huge fireball. (01:36:55)
Corrected entry: When Frost, the black guy, got bitten he turned into a vampire within a few seconds. After Jacob got bitten it took him half an hour to turn into a vampire.
Corrected entry: In the beginning of the film, after the actor credits have been displayed, they show a shot of the car that Richie & Seth are in. As it's coming down the road, you can see Richie's foot hanging out of the window. In the next shot, inside the car, his foot is inside and they don't show him putting his foot outside the window until a couple of shots later.
Corrected entry: After Sex Machine bites the trucker, the trucker throws Sex Machine through the door or wall, letting in all the vampires. But later, Seth needs Carlos to break the door down in order to let in the sunlight, killing all the vampires. What happened to the big hole made by Sex Machine when he was thrown outside? Why didn't that provide the sunlight needed to kill the vampires?
Corrected entry: When Scott is being sucked by the horde of vampires, Kate shoots him. This results in a big explosion. Scott may have had holy water in balloons strapped to his body, but the bullet fired off by Kate sure could not have triggered the explosion.
Corrected entry: It's never explained how Sex Machine's strap gun works. You never see him actually make something to let his gun pop out of his groin or to fire off shots. It sure cannot be operated by the force of telepathy.
Corrected entry: Seth, Scott, and Kate flee down the hallway to the storage area, pursued by the bats all the way and barely closing the door behind them. But when Jacob goes down the hallway (backwards, so the cross faces the main room), all the bats have emptied out into the main bar instead of trying to break down the door or waiting for the prey to inevitably stick its head out. Quite convenient, since Jacob can only point his weapon one direction at a time. (01:23:40 - 01:25:10)
Corrected entry: In the first big battle between vampires and human beings, the barkeeper attacks Sex Machine. The pistol attached to the belt pops out and fires off several rounds driving the barkeeper backwards. But you never actually see bulletholes exploding on the barkeeper's chest. (01:01:55)
