Everything You Always Hated In X-Men

15. The Absence Of The Animated X-Men Theme

The film left some fans disappointed right from the get-go, as X-Men's brief, CGI-laced opening titles sequence didn't feature the expected reprise of Ron Wasserman's iconic, even legendary theme from the 1990s X-Men animated series.

Not even a hint of that unforgettable theme is found in Michael Kamen's original score, which while certainly good feels a little lacking without even the faintest invocation of the single piece of music everyone associates with X-Men.

This was most likely a rights-based consideration above all else, but it still left fans crestfallen straight out of the gate.

In fact, it wasn't until the recent Doctor Strange in the Multiverse of Madness that we got to hear an orchestral version of the theme in a Marvel movie, when Professor X (Patrick Stewart) showed up in the film's infamous Illuminati sequence.
