X-Men: Days of Future Past is meant to be the culmination of the X-Men saga, aiming to bring the entire film franchise in full circle.
Set in an alternate and imaginative future, a band of deadly killing machines called Sentinels have been designed to adapt and overpower any mutant power imaginable, resulting to the mutant race facing extinction.
As a last ditch attempt to save what remains of the mutant race, Professor Charles Xavier (Patrick Stewart) with what remains of the original X-Men track down a small group of mutants led by his former students Bobby Drake aka Iceman (Shawn Ashmore) and Kitty Pryde aka Shadowcat (Ellen Page) who has the ability to send a person’s consciousness back in time. Upon finding them, Professor Xavier then reveals his plan of going back in time to prevent the Sentinel program from being enforced after Mystique (Jennifer Lawrence) assassinates its creator, Dr. Bolivar Trask (Peter Dinklage).
Instead of Professor Xavier going back in time, it is Wolverine (Hugh Jackman) that makes the journey because of his mutant ability to quickly heal and regenerate himself. Together with the younger Charles Xavier (James McAvoy), Erik Lensherr aka Magneto (Michael Fassbender), and Hank McCoy aka Beast (Nicholas Hoult), they track Mystique in a race against time to convince her that there is a far better path.
Although director Bryan Singer has done an outstanding job in delivering a thrilling and action-packed film in X-Men: Days of Future Past, he did fail to completely tie together the entire saga due to the many inconsistencies in the timeline. One notable inconsistency that is noticeable is the animonisty of the human race against the mutants, which resulted to the birth of the Sentinels. In the previous films that make up this saga, the government was shown to launch attempts for both humans and mutants to co-exist harmoniously with each other. This was highlighted with the installment of the older Hank McCoy (Kelsey Grammer) into a prominent position in the government. This inconsistency significantly puts the entire timeline of X-Men: Days of Future Past askew.
Another notable inconsistency in the timeline followed with Mystique. In X-Men: Days of Future Past, Professor Xavier explained that the Sentinels were born as a result of Trask and his team experimenting on Mystique to fully understand her mutant power of transformation. With him referring to Mystique always in the past tense, it is safe to assume that Mystique died as a result of the experiements done on her. If we follow this timeline, Mystique should not have then been able to play critical roles in the films The X-Men, X2, and X-Men: The Last Stand.
All is not lost, however. The film had been able to successfully bring the character of Wolverine in full circle, taking him from being the rogue and independent character introduced in The X-Men into a team player willing to sacrifice himself for the sake of the entire mutant race in X-Men: Days of Future Past. It also delve into the growth of Professor Xavier from being the rather proud mutant who saw the mutant race as the superior race in X-Men: First Class to the broken and utterly hopeless Charles Xavier in the film, culminating to the diplomat and wise Professor that has brought the X-Men together and united them into a solid team.
Despite the inconsistencies in the timeline from the saga and certain “mistakes” avid comics fans have noticed in the film, X-Men: Days of Future Past is nevertheless a thrilling and captivating film to enjoy and X-perience.
