I just (now) came home from an evening session of the film.
I need time to think about it - I think both Hayden Christensen and Ewen McGregor were great, but the rest of it left me a little cold. I went to the other two at midnight screenings, but I couldn't bring myself to face another late-night disappointment, so I waited until tonight (we're a day ahead of you guys).
I do remember sitting in the theatre wondering if it was directed by Michael Bay...
