Have to agree on Day the Earth Stood Still. I rented it because we usually watch Cruise movies but
I watched Serenity (2005) which was a sequel to the Fox sci fi series Firefly. It was kind of a fun sci fi romp with space battles and marauding cannibalistic berzerkers. And Summer Glau was in it.

I've had a crush on her since seeing her as a Terminator in the Sarah Conner Chronicles (if I were to die by machine, I'd want it to be her). I'd give Serenity a thumbs up if you don't expect high brow cinema.
