Continuity mistake: In the flashback of Rogue's father disowning her, when he says he's ashamed to be seen with her, the number of stripes on the flag on his hat decreases from six to four in the same shot. (00:13:08)
Continuity mistake: When Ms. Marvel first appears, her reflection is through the front window of the plane that Rogue is stealing. The lightning bolt design on her outfit and the red sash around her waist are not reversed in the reflection like they should be. (00:14:11)
Continuity mistake: When Rogue and Ms. Marvel crash-land into the ground, Rogue pushes Ms. Marvel to the side, with Ms. Marvel's hair being near the edges of the hole in the ground. When the shot changes, the edges of the hole are still in shot, but Ms. Marvel's hair is nowhere to be seen. (00:15:31)
Continuity mistake: When Pyro is unmasking Ms. Marvel, the wristband on Blob's right arm is missing. (00:15:37)
Audio problem: When Jean Grey exclaims "No!" after Ms. Marvel says "This ends now," she is speaking in Ms. Marvel's voice. (00:18:59)
Continuity mistake: When Rogue is visiting the comatose Carol Danvers in the hospital, Danvers' hair is parted down the middle and her bedsheets go all the way up to her neck. A couple of shots later, she has a lock of hair going down the middle of her forehead, and her sheets only go up to around her armpits. (00:20:17)
Factual error: At the end of the episode when Carol Danvers is shown comatose, there is an EEG machine next to her bed. This machine monitors brain activity and uses electrodes on the patient's head in doing so. She has no electrodes placed on her head, and the machine isn't detecting activity in her brain. (00:20:37)
Plot hole: In the season one episode The Cure, when Pyro and Avalanche are in the bar on Muir Island waiting for Mystique to arrive, Avalanche says "This friend of yours better show up soon or I'm going back to jail, just for something to do!" Rogue then comes in and Pyro suggests to Avalanche that Rogue could be Mystique, to which Avalanche responds "What do you mean it could be? Don't you know what she looks like?", leading Pyro to tell Avalanche that Mystique is a shape-shifter. This dialogue implies that Avalanche has no idea who Mystique is, which is further substantiated when Pyro and Avalanche kidnap Mystique later in the episode while she is in the guise of Dr. Adler, and Avalanche didn't recognize Mystique when she revealed her true form. However in this episode it is shown that Pyro and Avalanche were both previously members of Mystique's Brotherhood of Mutants, so Avalanche should already know who Mystique is without Pyro having to tell him. Rogue was also a member of that group yet neither Pyro nor Avalanche recognize her.
Other mistake: During a flashback, Rogue is shown absorbing Pyro's mutant power and then creating fire out of thin air. However, Pyro does not have the ability to create fire, he can only control it. That's why he wears a flamethrower on the back of each hand.
Continuity mistake: When Beast and Dr. Bohlson enter Carly's room, there is no breast pocket on Dr. Bohlson's labcoat. A couple of shots later, his labcoat now has a breast pocket with two tongue depressors in it. (00:02:25)
Character mistake: When Carly expresses her relief to Beast that he is fine after he was attacked by the anti-mutant group, he incredulously asks her how she knew he was a mutant. Aside from the fact that the Friends of Humanity were openly calling him a mutant in her presence when they accosted him, Carly was shown touching Beast's hand earlier in the episode. Despite being blind, she would also know that Beast's fur-covered hands would be quite different from the hands of regular people she might have touched. Given these facts, Beast should not have been surprised that Carly knew he was a mutant. (00:03:25 - 00:08:40)
Continuity mistake: The metal tubes on Wolverine's gloves appear and disappear when he is talking to Jean Grey. (00:04:19 - 00:05:07)
Continuity mistake: When Wolverine is infiltrating the Friends of Humanity's headquarters, and later when he is talking to Graydon Creed in their auditorium, some shots show him wearing a gold wristband on his left wrist, and other times he is not wearing one. (00:06:20 - 00:14:30)
Continuity mistake: The Friends of Humanity members have patches on the backs of their shirts/vests/overalls that say FOH, but when the two members are checking on Wolverine in the alley, their patches read HOH. (00:07:00)
Continuity mistake: The word-plate on the eye clinic director's office door is silver when first shown. A few moments later, it is the same color as the door, and the lettering isn't as bold. (00:07:45)
Continuity mistake: When Beast first enters Carly's room to tell her he won't be at her operation, she is not wearing any headphones. When the shot changes, she is suddenly wearing some. (00:08:15)
Continuity mistake: When Beast is looking through the photo album, it reads "Family Photos" on the front cover. When he tosses it to the floor, the "Family Photos" writing has now moved to the back cover. (00:09:35)
Other mistake: When Jean is bringing a tray of food to Beast, the liquid in the glass is not oscillating. (00:09:38)
Continuity mistake: When Beast throws the book at the mirror, his reflection remains stationary while he himself is walking towards the mirror. (00:09:50)
Continuity mistake: Just before the mirror shatters, Beast's reflection shows him burying his face in his left hand. When the shot changes, it is his right hand. (00:09:55)
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.
