The Avengers PG-13, 2 hrs., 13 mins.

It unleashes half a dozen superheroes on a baddie from another planet — but the best thing about this Marvel epic is that it also lets them loose on each other. B+ —Owen Gleiberman

Bel Ami R, 1 hr., 42 mins.

Robert Pattinson winces as a 19th-century man-about-town, leading a pretty cast (all looking stricken) in a lifeless period drama about love and social climbing. D —Lisa Schwarzbaum

Chernobyl Diaries R, 1 hr., 30 mins.

Want to vacation at the site of a nuclear disaster? Of course not. No one does — except for the six tourist victims in this okay-ish horror movie. B- —Clark Collis

Men in Black 3 PG-13, 1 hr., 46 mins.

Why return to MIB a decade later? Why, for a chance to time-travel back to 1969 and the pleasure of watching Josh Brolin just nail his turn as a younger version of Tommy Lee Jones’ Agent K. A- —Lisa Schwarzbaum

Moonrise Kingdom PG-13, 1 hr., 40 mins.

In Wes Anderson’s new fable under glass, it’s 1965, and a Khaki Scout (Jared Gilman) runs off to the wilds with the girl (Kara Hayward) he loves. A lot happens, but not a lot of it matters. B- —Owen Gleiberman

For a flick built around nudity and graphic gore, this one is shocking only for its joyless inability to embrace its own campy boobs-and-blood DNA. D+ —Kyle Anderson
