^ OK, so admittedly I've read very few original X-Men comics, but from my knowledge of the animated series, I know Exactly where that is from.....(I think...
)
Dark Phoenix. The story the animated series took the time to develop correctly (by doing the Phoenix saga first, not just going stright to dark), and one that the movie franchise is about to ruin for the SECOND time.... I really don't have a problem with the casting of most of the Fox/Marvel X-Men films, its just that after they made all the effort fix things in DoFP, they mucked it up again, irreversibly this time. I'm sure whatever Disney has planned in the coming years will be satisfactory, unfortunately by then the rest of their contemporaries in the MCU will be dead or retired, and the X-Men going toe-to-toe with newer/younger Avengers I don't care about is pretty sad.
There are no more good TV Shows, only ones that haven't disappointed me yet.
