My wife and I caught this at an XD Real3D theater today. I loved it. She thought after seeing all the build up movies, it took too long to get going. I don't agree. Not perfect, but very good to great. The conversion was the best I've seen in this hi rez theater. No lack of focus in the background, excellent depth and understated just as it should be. Some of the shots were outstanding. Some of the humor went right over the small audience's head. While the Hulk had some gotcha moments, I didn't think this portrayal was that different...subtlely different yes, but without the humor, not so much. Liked all the heroes, liked Loki, didn't love them. All in all, worth the $30.00 we spent and I'm glad we saw it. My wife got extremely ancy so I couldn't wait for the 2nd clip...someone want to put it in spoilers for me?
