I saw it in 3D and thought the effects were pretty amazing.
I had to laugh at Sca-Jo's character though. Everyone had these kick arse abilities/powers/contraptions and there she was, in a leather jump suit, basically just pouting sexily and sort of waving a....wait for it.....normal handgun. At giant alien machines. They could have at least given her the power to be invisible or something. Guess that would have detracted from her main ability - to have an epic hourglass figure and haughty pout.
I'd like to see women in action movies be a little more kick-arse and a little less arse.

If you'll excuse me I'm off to burn the remainder of my bras
