There's no denying the importance and impact of the original 2000 X-Men movie. As one of Hollywood's first serious attempts at a big-budget superhero film, its success proved the audience thirst to see these stories brought to life in live-action form.
It of course kickstarted a long-running X-Men movie franchise and encouraged studios to start buying up every popular comic book IP they could get their hands on.
And while X-Men remains a solidly enjoyable superhero movie today, it's also fair to say that not everything about it has aged spectacularly.
On the flip-side, there are some things about 2000's X-Men that we've all hated ever since the film first came out, whether we wanted to admit it or not.
From glaring deviations from the source material to weird continuity errors, not one but two terrible accents, and a certain line of dialogue that still makes fans groan, these 15 moments drag down a film that otherwise gets so, so much right.
No movie is perfect, and sequel X2 certainly learned from a lot of the original's missteps, even if those gaffes remain major sticking points when watching the film now...
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.
