Other mistake: After Magneto says "Trust me, you'd rather not know," a hole appears in his pants around his right hamstring and then quickly disappears. (00:02:50)
Other mistake: When Xavier asks Magneto how much further they have to reach the top of the cliff, Magneto tells him he would rather not know, suggesting they still have a long way to go. However, in the wideshot of the sky-riders flying in to attack the two, you can see Magneto is about three times the length of his own body from the top, and according to the book "X-Men: The Art and Making of the Animated Series," Magneto is 6 feet tall. This means he is only about 20 feet, give or take, from the top, which isn't all that far in terms of climbing a cliff. (00:02:44)
Mojovision - S2-E11
Other mistake: When Jean is trying to dodge Spiral's teleporting blast, she ends up tripping on a power cord running across the floor. An electronics store wouldn't have a power cord running across its floor for this very reason. They would be begging for a lawsuit if they did. Her foot is also closer to the wall in the first shot than in the second shot. (00:07:30)
Other mistake: When Jean is bringing a tray of food to Beast, the liquid in the glass is not oscillating. (00:09:38)
Other mistake: When Rogue is hovering above Muir Island, she pulls out a book to confirm she's in the right place, and the picture of Muir Island in her book shows it to have three smaller islands on its south side. When she lowers the book to look at the actual island, only the large island shown on the southwest side in the book is there. She's only hovering a few hundred feet above the island, so even though the other two islands were small, they should still be visible. (00:09:48)
Other mistake: When Rogue begins flying towards Cable after disarming him, she is only about 30 feet away from him. As she is flying towards him, he takes the time to pull a plasma grenade from his belt, pull out the pin with his mouth, and then throw it at her. In the time it took him to do all of that and given the speed at which Rogue was flying towards him, she should reach him well before he could throw the grenade at her. (00:18:05)
Other mistake: When Gambit, Storm, and Jubilee get into the back of the taxi, you can see the window seat behind the driver is unoccupied, which would suggest the three of them are occupying only two of the backseats. (00:12:51)
Other mistake: When Wolverine is walking around the camp after Sabretooth attacked it, he doesn't leave any footprints in the snow, even though Sabretooth's footprints are there. (00:14:52 - 00:15:36)
Other mistake: When the helicopters are attacking Magneto, they are firing their guns at him, and then he destroys them, at which point you can see the occupants parachuting away at the same time the helicopters explode. There's no way they could have been operating the guns and then jumping out of the helicopter to safety in one second. (00:06:01)
Family Ties - S4-E17
Other mistake: This series is in the same continuity as the other Marvel animated series that aired around the same time - Spider-Man, Iron Man, The Incredible Hulk, and Fantastic Four - by virtue of each aforementioned show crossing over with at least one of the other shows. However, in Iron Man, Scarlet Witch has an Eastern European accent, and in this episode she has an American accent.
The Phoenix Saga (2): The Dark Shroud - S3-E4
Other mistake: After the shuttle crashes into the Upper New York Bay, the X-Men escape the wreckage and swim up to the surface, with Wolverine being the first one to appear. Given that Wolverine's skeleton is coated with a heavy metal, not only should he not be the first one to surface, he should actually sink instead. (00:04:06)
Night of the Sentinels: Part 1 - S1-E1
Other mistake: In the scene where Professor X uses his psychic powers to deduce that Jubilee is trying to escape the mansion, there is a semi-dissolve edit that simultaneously shows a close-up of Professor X with his left hand on his forehead and a counterpart image of Jubilee hiding around the corner. If you look closely at Professor X in the counterpart image of Jubilee, his left arm and hand are shown to be on his hover-chair's armrest and not his forehead.
Answer: It appears a number of factors led to its demise. It was originally intended to air for 65 episodes, but its popularity extended that. However, there were continual production quality problems, issues regarding whether the content was suitable enough for children, as well as financial considerations that finally led to it being ended.
