Sandra Bullock and George Clooney in GravityGRAVITY

Alfonso Cuarón's space thriller Gravity opened this past weekend, and if you haven't seen it yet, you really should. Like, now. I'm serious. Step away from whatever electronic device you're using to read this and get in line at the cineplex - or, if the cineplex isn't currently open for business, drive over there and wait. Don't be one of those people who procrastinates until the movie hits home video and then whines about missing it on its initial release. Because I'm telling you: You're gonna want to catch Cuarón's latest on the big screen, and preferably on the biggest screen possible with your 3D glasses firmly in place. No kidding, folks: This thing is going to blow your mind.

James Hetfield in Metallica: Some Kind of MonsterMETALLICA: SOME KIND OF MONSTER

Metallica: Some Kind of Monster has the sort of title guaranteed to repel viewers who might love it the most. This warts-and-all documentary, chronicling the two-plus years devoted to creating Metallica's St. Anger CD, is like the best episode of Behind the Music ever made, offering an intimate look at the relationship between guitarist James Hetfield and drummer Lars Ulrich, and detailing the nightmare involved in getting the group recording again after a five-year hiatus. The movie will be Mecca for metal fans, yet its appeal isn't totally insular. Audiences who may be loath to sit through a doc on any heavy-metal group might not realize what directors Joe Berlinger and Bruce Sinofsky have fashioned here; Some Kind of Monster is one of the finest recordings of the collaborative artistic process ever committed to film, a hard-edged and endlessly fascinating look at the excruciating work that goes into the making of an album. And for those for whom documentaries are even less appealing than heavy metal, it must be said that the film is one of the funniest and most shockingly touching screen works of the year, This Is Spinal Tap with actual human beings at its core. It's a thrilling experience.
