Leave it to the X-Men to put the fun back in summer blockbusters. Hugh Jackman, in the role he was coiffed to play, and the rest of the crew from pretty much every film in this past, present and future franchise, deliver the action and the laughs in "Days of Future Past," an all-star/all-X-Men outing designed to transition from the aging first generation cast into their younger selves. It's too long and so cluttered with characters and exposition that if you aren't a fan of the comics, you may feel you're being punished. But it delivers the 3-D thrills and the Wolverine (and Quicksilver) giggles, and how. In a "Terminator" future, the robotic Sentinels have all but wiped out humanity and the mutants who love them. But with the aid of time-bending Kitty Pryde (Ellen Page), the X-Men may be able to stop the mad - or at least greedy and irritable - scientist (Peter Dinklage) who invented these machines back during the Nixon administration. Future mutants send the greying Wolverine (Jackman), or at least his consciousness, back to 1973. And from the minute the guy wakes up in a world of lava lamps, Little Feat and Lectric Shave, things are popping. Professor Xavier (Patrick Stewart) and his nemesis-turned-ally Magneto (Ian McKellen) need Wolverine to convince their feuding young selves (James McAvoy and Michael Fassbender) to prevent a vendetta by Raven/Mystique (Jennifer Lawrence) that dooms the future. So Wolverine, Beast (Nicholas Hoult) and the two mutant leaders contend with the Vietnam War peace talks, Richard Nixon, as well as the young soldier (Josh Helman) who will age into the evil Stryker as they chase Mystique hither and yon.
