I went to see the friday-night midnight showing with a lot of cowworkers and liked the movie a lot considering that sort of thing is not my bag baby.
The 3D was not your run o the mill red/green glasses. A polerizeing effect similiar to what you find in the theamparks in the way of 3D is used so they need to have a special 3D screen settup. It wont be released in 3D everywhwere I suggest you see it somewhere that it is shown in 3D I can see how it would make a big difference in perception of this movie. (Then again I went in with 0 expectations)
Oh and I know about 20 people with screen credits not working for the mouse...
The DJ team from whateverthefvck radio station that hosted the pre-event blew so bad that perhaps the movie got a bump from not being them though.
