You simply. Must. See it.

I enjoyed it all except for two things: the part where the young James T. Kirk drives that gorgeous 'Vette off the cliff (sniffle, may the C2 rest in peace), and the substandard sound system in the theater where it played. All's well that ends well, though, 'cause I'll get to see the Imax version this week! [cue ear-to-ear grin]

The only physics goof that jumped out at me was in a scene where three good guys are plummeting through the atmosphere having jumped from orbit. They're headed planet-side at a hefty clip through an atmosphere thick enough for a parachute to be effective, but they didn't turn into human meteors. Strange, that.

Phil Plait has a Bad Astronomy review up; this movie rocked so hard Phil might want to rename his site Bad-Ass Astronomy.
