8. X-Men

Remember I didn't say the BEST movies, I said the most important ones.

That first X-Men movie may not hold up that well but"”well, okay, it might not hold up at all, but it is still an important part of the landscape of superhero cinema. The visual aesthetic shaped the costume designs favored for quite a long time afterwards.

Not even counting the fact that the franchise would go on to be a superhero movie frontrunner for a long time, the film is still important. Casting seriously talented actors like Patrick Stewart and Ian McKellen really brought the genre to new heights that would be the norm for the foreseeable future.

An okay movie, but one whose success opened the doors for much better ones.
