Deliberate mistake: When Johnny is watching the news footage of the Hulk battling Thing, all the footage is merely clips from that portion of the episode, including parts of the battle that were happening before the camera crews even showed up. (00:02:50 - 00:07:20)
Behold, a Distant Star - S2-E10
Revealing mistake: When the heroes are in the Fantasticar looking for the Skrulls, they fly by the same group of three buildings seven times, and from two opposing camera angles. (00:15:02)
Behold, a Distant Star - S2-E10
Revealing mistake: When the Fantasticar is beamed to the Skrull home world, the edge of an animation cel is visible on the right side of the screen in the shot of the beam shooting out of Earth. (00:15:26)
Behold, a Distant Star - S2-E10
Continuity mistake: When Sue is talking about her father going into hiding, the camera is on the right side of a photo album, showing a newspaper clipping of him being wanted for murder. When the shot changes, the contents of that page are now three different photographs. (00:07:32)
Behold, a Distant Star - S2-E10
Character mistake: When Sue is brought out of surgery, her father can be seen wearing a watch. Surgeons don't wear watches or any other kind of jewelry when performing surgery, as they can't be sterilized and can also get in the way of gloves. (00:05:00)
Revealing mistake: When Silver Surfer is flying between the buildings with the Statue of Liberty in the background, the building on the right briefly vanishes from the screen. (00:00:55)
To Battle the Living Planet - S2-E6
Continuity mistake: This series is in the same continuity as the other Marvel animated series that aired around the same time - X-Men, Spider-Man, Iron Man, and The Incredible Hulk - by virtue of each aforementioned show crossing over with at least one of the others. This episode, which originally aired on November 4, 1995, features a cameo appearance by She-Hulk. However, Jennifer Walter's didn't become She-Hulk until the season 1 episode of The Incredible Hulk entitled "Doomed," which originally aired on November 3, 1996. We know "Doomed" takes place after this episode, because the later episode of this series, entitled Nightmare in Green, features a plot where Dr. Doom meets Hulk for the first time after discovering that he is also Bruce Banner, and attempts to use him to destroy the Fantastic Four, and "Doomed" showcases Dr. Doom once again trying to use the Hulk to suit his own ends.
Behold, a Distant Star - S2-E10
Continuity mistake: When Franklin Storm is telling his children not to cry, Sue is stroking his hair with her right hand. When the shot changes, her right hand is resting in front of her right leg. (00:14:08)
Plot hole: When Frankie tries to get Johnny to chase her out into space, he tells her he can't follow and warns her to turn back due to the thin atmosphere not being able to keep their flame powers active, and indeed her flames die out, and she begins falling back to Earth. However, several minutes later in the episode, both of them are just outside of the Earth when Terrax arrives, and again at the end after she becomes the new herald of Galactus, Johnny follows her into space well beyond Earth before his flames die out. (00:03:15 - 00:06:03)
Revealing mistake: When Nova blasts through the building, the wall where the hole is created has already been drawn as misshapen and discolored, likely to make it easier for the animators to animate. (00:02:53)
Prey of the Black Panther - S2-E7
Audio problem: When Black Panther is saying "The Black Panther's ready to stalk again," he doesn't press his lips together when saying "Panther" in order to produce the "P" sound. (00:21:12)
Prey of the Black Panther - S2-E7
Factual error: When Reed is looking at the radar image of Africa, he states the blip on the radar is in equatorial Africa. However, the blip appears around where Namibia is, which is more than 1,500 miles south of the equator. (00:05:54)
To Battle the Living Planet - S2-E6
Factual error: The Moon is around 238,000 miles from Earth, but when the Fantastic Four go out into space to find Thor, the Moon is extremely close to Earth. (00:04:11)
The Silver Surfer & the Coming of Galactus: Part 1 - S1-E5
Continuity mistake: When Reed is stretching up to speak to Galactus, the black 4 on his chest briefly turns white. (00:20:04)
The Origin of the Fantastic Four: Part 1 - S1-E1
Other mistake: When Puppet Master is making a clay figurine of Thing, the mold he uses doesn't have a Thing-shaped interior with which to make a detailed figurine. The figurine should have just looked like an undefined human-shaped figure. (00:15:20)
The Origin of the Fantastic Four: Part 1 - S1-E1
Plot hole: The beginning of the episode shows video footage for Dick Clark's telethon of the Fantastic Four battling Namor underwater. However, the Fantastic Four didn't even meet Namor until the third episode of the series. (00:01:00 - 00:02:02)
To Battle the Living Planet - S2-E6
Other mistake: This series is in the same continuity as the other Marvel animated series that aired around the same time - X-Men, Spider-Man, Iron Man, and The Incredible Hulk - by virtue of each aforementioned show crossing over with at least one of the others. However, early in this episode, the Fantastic Four receive help from the Avengers, and two of their members are Iron Man and She-Hulk. Iron Man is not a member of the Avengers in this universe, he is a member of Force Works. She-Hulk is not a member of the Avengers either. She is an attorney and is also frequently off doing missions with Bruce Banner/Hulk. (00:01:52)
Incursion of the Skrulls - S1-E4
Continuity mistake: The Fantasticar's light shining on the Skrull projection device changes color between shots. It is initially yellow and changes to blue.
The Origin of the Fantastic Four: Part 2 - S1-E2
Continuity mistake: During the recap, it shows the man on the bridge step off the ledge and start to fall before Johnny grabs him. However, in the previous episode, Johnny grabs him while he's still on the ledge.
Answer: Gleaned from the Internet: Much of the negative reaction was due to the poor, simplistic, and outdated quality of the animation where the characters moved stiffly and clumsily through scenes. There were also some obvious animation compositing gaffs. The animation colors were also criticized as being overly bright and cheery and out of character to the established story's darker tone. The broad humor of the first season was replaced by a more mature narrative between the characters.
