Still catching up with the thread but all in all a solid start. Originally had it at IM3 numbers then 180 and after the reviews 190. OS numbers were pointing around 180. So overall, it met my earlier expectations. I still think that this has a good chance to beat AoU for final DOM.
As as for marketing. Yeah it was pushed as Avengers 2.5. The cast, press tours, posters, ads (United We Stand...). Hard not to see that they were pushing Cap v Iron Man. The movie itself though is still very much a Captain America movie, with a lot of supporting character, and a great one at that.
Catching it again tonight at 7:30 and may watch with brother and sister in law tomorrow.
