OH MY GOD!
Just got back from an IMAX session on opening night. Our showing was booked out, full house. As was the session after. I suspect the later showings were as well.
Amazing film. Great characters, intense action and suspense, amazing effects - everything you could possibly want IMO..
The audience were really into it. Lots of people in the packed cinema laughing out loud in spots, gnashing their teeth in others (and on occasion doing both at the same time) sighing with delight when old Spock turned up and giving the film a warm ovation at the end.
Really cool experience. It's been worth the wait. Star Trek is back with great big gigantic balls.
