El D! - I watched it, too, in 3D last night; I'm for sure going to see it again some time soon!
It actually was my first 3D expierience at it was really great; I enyoed every minute of it same as you describe, and everybody did not believe it was such a long movie!
Btw. it was the quietest movie theater I have been to in a long time, too, seems like others where impressed just the same...
