I know it is "cool" or "stylish" to reject 3D out-of-hand....
However, I will remain open to the tech.
Whether or not it works for the film in question (or any other), I just don't know.
IMO (and it is just an OPINION), 3D is a tool...and is only only as good as its user (i.e.: Avatar)....
The Avengers may be a kick in 3D...or not, I just don't know.
Unless some of our regular guys (whose opinions I respect) say it "sux," I'll probably spring for the 3D ticket.
Swine are good people too.
