Just seen it at the London IMAX. There were moments when I was simply in awe or just saying "jesus!" at what was happening. That entire sequence with the collapsing building is without doubt the greatest action sequence Bay has put on film.
I'm glad the goofy humour was dialed back, though there was still a bit too much in the first hour. That aside, this is the biggest and most spectacular action film ever. Not necessarily the best but definitely the most visually astonishing.
