X-Men: Days of Future Past

Once storytelling franchises have been around awhile — especially ones involving science fiction and/or superheroes — it can be hard for filmmakers to find enough creative real estate to let their imaginations sprawl. After all, histories have been set, great and terrible deeds done, characters evolved or killed off, and it's a bad notion to retread over familiar territory.

So what to do? More and more, these movies are going retcon.

Retconning is when a new set of creators essentially reboot everything we know about a mythos, blanking the slate so they can start over from a zero point of their own choosing. "Star Trek" did this recently, and now the X-Men comic book heroes have, too.

This bold new film, the best superhero flick since "The Avengers," looks at a post-apocalyptic world where nearly all mutants have been destroyed by the menacing robotic Sentinels. Clawed, nearly unkillable warrior Wolverine (Hugh Jackman) is sent 50 years into the past to occupy the mind of his younger self, and must convince the Professor X of that era (James McAvoy), who is wallowing in a pit of self-pity, to take action to prevent the terrible tide.

That means diverting power-mad frenemy Magneto (Michael Fassbender) and shape-shifting skullduggerer Mystique (Jennifer Lawrence) from their mission to make mutants the master of regular humans rather than the object of their hatred. Needless to say, they're not happy to go along.

There's one scene that may just be the most entertaining action sequence of the summer, and it involves a new mutant named Quicksilver who is so fast he practically lives in his own dimension of time.

A satisfying mix of action, convincing characterizations and plot twists, "X-Men: Days of Future Past" delivers one for the ages.

Video extras are quite hefty, and include deleted scenes with audio commentary by director Bryan Singer, a gag reel, a gallery and several making-of featurettes.
