Paul Giamatti and Thomas Haden Church in SidewaysSIDEWAYS

Alexander Payne's Sideways is so chockfull of good humor and emotional accuracy that you leave the theater overwhelmed and a bit giddy; it feels like a movie that you, alone, discovered, and want to share with friends immediately.

Shia LaBeouf and Will Smith in I, RobotI, ROBOT

I, Robot is perfectly titled, because it's about as mechanical and impersonal as Hollywood entertainment gets. That's not to say it's completely unenjoyable - Alex Proyas' sci-fi work, inspired by a series of Isaac Asimov stories, features some nifty set pieces, including an exciting mid-film sequence involving a hundred 'bots doing considerable damage on an underground freeway - but the film progresses with so little inventiveness that you'll have better luck tallying up the film's numerous influences (Blade Runner, A. I., Minority Report ... ) than finding an original idea.

Josh Hartnett and Harrison Ford in Hollywood HomicideHOLLYWOOD HOMICIDE

During Hollywood's Summer Blockbuster season, we critical types generally spend three months bemoaning the tired, formulaic scripts that inevitably lead to tired, formulaic summer movies, and when we do find something worth sitting through - The Matrix Reloaded, say, or X2: X-Men United - it's almost always despite the banality of their screenplays. (Which makes the release of a Finding Nemo, in which the brilliant execution is matched by an inspired script, even more miraculous.) Who cares about inventive plotting or smart dialogue or even basic coherence if, instead, you get to watch Keanu Reeves tussle with a hundred Hugo Weavings? Undemanding, turn-your-brain-off-and-enjoy entertainment certainly has its place, and even those of us with a particular aversion to Hollywood Blockbusters might be inclined to be a bit more generous than usual in our appraisal of empty-headed summertime escapism.

Steven Culp, Kevin Costner, and Bruce Greenwood in Thirteen DaysTHIRTEEN DAYS

Just because a movie is smart doesn't mean it'll avoid dullness. Roger Donaldson's Thirteen Days, which documents the terrifying two weeks of the Cuban Missile Crisis, is evidence of this, a well-scripted, well-acted drama that might still cause you to doze off.
