Here's what I recall from the movie:
Did I mention one of those groups had people standing?
Well, the movie appeared to be fabulous. Amazing.
And that's why we left.
We might go to the cinema again today and demand our money back.
I will definitely see that movie, eventually. I was really enjoying it (we left about after half an hour).
Why didn't we do anything about it? Well... it's not very dificult to convince *one* guy to shut up...
But the whole theatre? I'm not that good.
I went to see the movie with no previous knowledge about it, and I really do believe that's part of why I was enjoying it so much.
It did feel weird to have my hands in my ears and trying to make some noise while they were showing the trailer for SWIII, though...
