OK, so I just came back from watching this movie as it premiered thursday and I must say I was very pleasantly surprised by what it was, i was expecting a rushed mess of crap Xmen 3 style, but the movie has good pacing and is IMO one of the best superhero films out there.
I paid for the 3D but you could watch this movie without it (I like watching movies in 3D). The effects are not gimmicky in your face coming at you crap, its just there to add to the ambience.
All heroes get some decent screen time and while the movie has some gags and punchlines they come out good and not corny IMO.
The effects are top notch and when the action kicks in you are in for a treat. This will totally be worth your time if you are into this kind of thing, Id rate it 9/10.
P.S: As usual for Marvel movies, stay after the credits
Oh and Hi everyone....
