Just saw "Sucker Punch" tonight. Interesting. Unfortunately, I can see why it got a bad review as what's happening and why, isn't terribly mysterious. If y'all just let the ol' "suspension of disbelief" take hold and one just enjoys the action, it's well worth watching.
Frankly, I got the impression it saw things from a heavily female perspective "Yep, me and my posse, a buncha gorgeous chicks who kicked evil-guy/evil-robot butt with enthusiasm" seems to have been to motivating idea behind much of the flick.
