The one thing that always bothered me about the OG X Men show was the stiff ass animation and Storm's high and mighty trembly voice when she used her powers, both of which are well illustrated in the clip above.
The character designs were good, but it lacked the fluid animation style of Batman TAS and Superman TAS. Storm irritated the fuck outta me every time she spoke. Oh, and that Morph cat they just made up for the show was stupid.
There was one decent moment in that show, the episode where Bishop returned and wound up face to face with Cable. I remember really liking that episode.
I still watched it every Saturday in college. That and Batman TAS could be heard all up and down the halls in the dorms every Saturday.
