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.

Ellen Page and Jesse Eisenberg in To Rome with LoveTO ROME WITH LOVE

After Woody Allen's rather staggering success with Midnight in Paris - personal-best box-office, the man's first Academy Award in 25 years - I guess it was inevitable that critics, as a whole, would greet the filmmaker's follow-up project with a collective "meh." And that's certainly happened with Woody's new To Rome with Love. (Not that it matters, but the comedy is currently sitting with a "45-percent fresh" rating - i.e., "not fresh at all" - at the review aggregator RottenTomatoes.com.)

Justin Bieber in Justin Bieber: Never Say NeverJUSTIN BIEBER: NEVER SAY NEVER

Leave it to that great Socratic thinker Ozzy Osbourne, in a recent TV commercial, to ask the question that's been on many a middle-aged mind of late: "What's a Bieber?"

JONAS BROTHERS: THE 3D CONCERT EXPERIENCE

(With apologies to my godchild Jordan, who is surely the most rabid Jonas Brothers fan I've yet met. Sorry, sweetie. Just remember that I'm a bitter, cranky old man.)

Dave Chappelle in Dave Chappelle's Block PartyDAVE CHAPPELLE'S BLOCK PARTY

Dave Chappelle's Block Party is teeming with something that has been sorely absent from 2006's movie crop: joy. In the late summer of 2004, Chappelle, fresh from signing his now-legendary - and currently defunct - $50-million contract with Comedy Central, spontaneously decided to throw a block-wide bash, and recruited a batch of rap and R&B performers (including Mos Def, Erykah Badu, Kanye West, Jill Scott, and Lauryn Hill and the reunited Fugees) to perform a day-long gig in Brooklyn; the resulting concert doc features highlights from the concert interspersed with scenes of Chappelle kicking back with the stars and the block-party attendees, and the movie, directed by Michel Gondry, is a giddy, oftentimes exhilarating spectacle. It's hard to determine who's having more fun - the musicians, whose on-stage performances are heartfelt and vital; the Brooklyn masses, whose enjoyment of the show is palpable; or the movie's audience.
