Saw it already (press projection, thanks to a friend).
Very spectacular, great action scenes, nice characters, interesting story, but average 3D,...
Nothing stellar, but it's still a really enjoyable movie.
But don't bother paying more for the 3D, I don't know if it was because of the projection in my theatre, but it wasn't great... I had a good time, and I would watch it again.
7,5/10
EDIT :
Also, to my surprise, the movie is quite funny.
(Not really a spoiler, it's implied in the trailers, but you never know): Tom Cruise dies A LOT in this movie, so it allowed the filming crew to create some really funny situations. It won't send your sides in orbit, but I actually laughed watching it.
Just because you have an opinion doesn't mean you are necessarily right.
