X-Men: Days of Future Past (2014) is not your typical 'casually-walk-into-for-a-matinee-without-seeing-the-pervious-five-movies-in-the-series' kind of film. It's fast-moving, all-encompassing, genre-bending, fanboy kind of film.
It begins at an unspecified year in a dark future where a government project, know as Sentinels, has gone awry, systematically wiping out mutants AND humans with the dormant mutant gene in their DNA. Wolverine (Hugh Jackman) must to go back in time, with the help of Kitty Pryde (Ellen Paige) and the rest of the still-living mutants, in order to convince a young Professor X (James McAvoy) and Magneto (Michael Fassbender) to join forces and unmake the dismal future he came from.
Certainly, things separated this particular X-Men film from the rest of the series: a lack of over-the-top and cartoonish villains and henchmen, simply explained time travel, and blurs the lines between the 'bad guys' and 'good guys' better than most comic book films.
Granted they merely maintained continuity with the pervious films in the series, but with an ensemble cast that would put a combination of Valentines Day and New Years Eve to shame, the roles that stole the show were a surprise.
Quicksilver (Even Peters) was a far more memorable character than anticipated. With screen-time that barely surpassed fifteen minutes, disappointment rippled through the audience when it became clear he wouldn't be in the bulk of the action as the film progressed. The audience even burst out laughing during a beautifully shot slow-motion scene when he single-handedly saves the young Professor X and Magneto from death at the hands of plastic-gun-wielding government employees.
Yet, there were things that should have been done differently. Namely, the pace. In the first ten minutes, we go from New York, to Moscow, to China, and then to the 1970s. They only had a little over two hours to pack in what one could consider anywhere between two and seven comics worth of material, so needless to say, they had to glaze over some stuff.
And then there is the villain, or villains, if you will. Without using spoilers, the film does what few comic movies ever do: toy with the idea of who is truly the villain from beginning to end. Absolute evil is only manifested in the non-human Sentinels, and absolute good in the relationship between Charles Xavier, Logan, and the mutants with compassion for humanity.
Overall, if you're already a fanatic of all things X-Men, it's a movie worth seeing (albeit not necessarily in theaters). If not, don't waste your time or wait until it's on FX.
