I just saw X-men: Days of Future Past, and I have to say it’s probably the best X-men film by a large margin. It’s not a superhero film, and deviates wildly from the original comic storyline, but I’d argue those are it’s strengths, not its weaknesses.
Overall, it’s a character-driven science fiction film that involves superpowers, as opposed to a superpowered science fiction film. The powers serve the story and provide nice visuals, but everything important comes from the very human characters making decisions based on their own goals and flaws, which is how it should be. The climax is one of character more than action, and surprised me with how it came together- always a plus.
The deviations from the original comic also work very well for the story it is. This isn’t a team-based superhero wrestling match, so using Wolverine as the focus works better than Kitty and keeps things at a more human level. None of the “good guys” are really high powered, and it keeps them at a disadvantage throughout the film, again, keeping powers from dominating the plot.
And the ending ties everything to date up in a nice bow, while leaving the future open for a new continuity. Good work all around!
