Revealing mistake: When Warren's girlfriend is looking for him in his lab, she is startled by Cable who is hiding behind the door and slams it shut once she enters the room. When she is startled and looks back at Cable, the animation is not very fluid. As she is turning around to look at Cable, her "onion skin" form remains, making it look like there are two of her. (00:03:35)
Continuity mistake: When Cable blasts Warren off the balcony, Warren falls and drifts into the snow a couple feet, leaving an impression of his shape in the process. When he recovers, he emerges from completely under the snow as if he were buried, but the impression is still there in the snow moments later when he retreats, so it could not have refilled itself with fresh powder and buried him. (00:03:10 - 00:04:30)
Continuity mistake: When Cable grabs Warren through a shelf on his bookcase, he knocks several books onto the floor. When Warren pushes the bookcase over, there is an overhead shot of the floor surrounding the bookcase for several feet in each direction and there are no books visible on the floor. (00:02:50)
Continuity mistake: When Warren shoots his blaster through the bookcase, the blast goes through some books/file folders that say "DNA Test 6" and "DNA Test 7" while "DNA Test 4" and "DNA Test 5" are warped out of shape. When he pushes the bookcase over, the two warped books/file folders are back to normal. (00:02:50)
Continuity mistake: When Warren's girlfriend is saying "They say you keep a mad scientist up here," the earring on her left ear goes from being comprised of five gray circles, to four, and then back to five in the same shot. Both of her earrings are then comprised of four circles for the remainder of the scene. (00:02:10)
Slave Island - S1-E7
Other mistake: When the Leader is backing away from Cable, his right hand and right foot pass through a puddle of water, but the water does not react to the movements. (00:19:05)
Slave Island - S1-E7
Continuity mistake: After Gambit jumps out of the moving hovercar, it comes to a stop in the middle of the road. When the shot changes, the hovercar is suddenly on the left side of the road (note the yellow lane dividers), and is no longer casting a shadow. (00:12:00)
Slave Island - S1-E7
Continuity mistake: When Gambit tries to grab the gun, Cable stops him by placing his left foot on top of it. When the shot changes, it is now Cable's right foot that is on the gun. Additionally, yellow lane dividers in the middle of the road disappear when Gambit first reaches for the gun, and then reappear a couple of shots later. (00:12:15)
Slave Island - S1-E7
Continuity mistake: When Storm is asleep, her lightning bolt earrings appear to be connected through the back of her earlobes. When she wakes up, the earrings are now on the front of her earlobes. (00:20:15)
Slave Island - S1-E7
Continuity mistake: When Cyclops is trying to radio Professor X from the Blackbird, there is a window immediately to Cyclops' right. When the shot changes, Jean Grey is suddenly seated on Cyclops' right. (00:20:00)
Slave Island - S1-E7
Audio problem: When the giant wave of water from the burst dam is heading towards Cable, Hodge and the Leader, Cable begins laughing maniacally. After the wave crashes down on them and floods the area, you can still hear Cable laughing even though he should be submerged underwater. (00:19:25)
Slave Island - S1-E7
Continuity mistake: When the Genosha guard tries pulling a gun on Cable, you can see his headgear only extends down to his jawline and chin. When Cable picks him up and throws him, his headgear is now also covering his entire neck. (00:19:00)
Slave Island - S1-E7
Revealing mistake: When Storm is saying "There will be thousands of them," her mouth briefly disappears from her face. (00:16:45)
Slave Island - S1-E7
Continuity mistake: When Cable shoots his exploding plasma blast at the conference table, the blast is shown coming through the window from a downward angle. However, the tree branch that Cable is subsequently shown to be using as his vantage point is lower than the window, so the blast could not have come at a downward angle. (00:14:45)
Slave Island - S1-E7
Other mistake: After Cable shoots his exploding plasma blast at the table that Gyrich, Trask, Hodge and the Leader are sitting at, the former three all evacuate the area while the Leader is still shown to be sitting at the table only a moment before it explodes, but he does not suffer any ill effects from the concussive blast or wooden shrapnel. (00:14:45)
Slave Island - S1-E7
Continuity mistake: When Gambit is carrying Jubilee over his shoulder, the placement of his hand alternates between being on the small of her back, the back of her thighs, or her butt depending on the shot. (00:13:55)
Slave Island - S1-E7
Audio problem: When the decapitated Sentinel body crashes to the ground, the sound of it crashing against the concrete is too soft for its size. It sounds like something slamming against a metal appliance when it should sound more like a car crashing into a wall, only louder. (00:13:50)
Slave Island - S1-E7
Continuity mistake: After Gambit unlocks his collar, he lets the collar fall to the ground. In the next shot, the collar is visible on the ground a couple feet in front of him. In the shot after that when he retrieves the gun, the collar is no longer visible on the ground. (00:12:50)
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.
