I think I liked this movie less than everyone else. I find it so packed with stuff that it's exhausting to even discuss. I still enjoyed the movie, but felt the action was weightless and fake and the characters and storylines didn't have any room to breathe. Motivations of several Avengers and villains are unclear or under-developed.
Right now you've seen it I can agree with your POV Dave, you've captured my thoughts exactly, I found it hard to follow, I'm not really sure what I found difficult about it but it was just akward to me.
I enjoyed it don't get me wrong, and I didn't want to give an honest opinion in case it affected your enjoyment of it but now you've seen it, I think I enjoyed the first film more..maybe even GOTG more.
