Just got back from finally seeing this. Thought it was really just ok. It definitely wasn't as bad as some of the more negative reviews made it out to be, but it also didn't amaze me at all.
First, I'll start with the positives. I thought Ultron was awesome. Easily the best part of the film was James Spader's voice acting, he really brought the character to life (although I couldn't stop picturing Robert California saying some of those lines in the Dunder Mifflin conference room
). I wish they would have elaborated on his motives a little bit more. The few times that he was somewhat humanized or showed emotion were really great but I wish there was more elaboration on those moments. I also thought Jeremy Renner really shone through in this movie. He's one of my favorite action actors and it was really nice to get an expansion of his role, especially considering how under-utilized he was in the first Avengers.
Now to the critiques. First off, we get it, they're trying to save people. I understand that it was mainly a function of the plot (trying to get people off the floating land mass), but good Lord did they beat that point to death. Unfortunately I had read the Whedon quote about wanting to distinguish AoU from Man of Steel by showing the team actively trying to save people, but even had I not read that I still think it would have been excessive. Also, I thought the dialogue and attempts at quips and jokes were eye-roll worthy. I laughed maybe once the entire movie. I can appreciate humor and can recognize attempts at humor, but very very few of the remarks landed with me at all. The dialogue itself was incredibly cliche and cheesy, which is sort of to be expected, but there were many times where I cringed at either the actual words or the delivery of the lines themselves. Finally, Whedon continues to underwhelm shooting action sequences. I did think that the slow-motion group shot in the church at the end was VERY well done, but there were many times where it seemed like we were seeing the same shot over and over with slightly different action, especially regarding camera angle and the scope of the shot.
Overall, I thought it was alright. I truly tried to go in with an unbiased frame of mind, but it just did not hit home with me at all. It's basically the same formula Marvel has always had: fun action movies. And that's fine, but eventually I think they're going to have to try their hand something a little more serious, expanding on the tone they set in Winter Soldier (which is probably my favorite Marvel movie).
The mid-credits teaser was also cool. Really looking forward to Thanos. Hopefully he doesn't have an army of faceless underlings like Loki and Ultron both had, which I also thought was a detraction in that the two villains were too similar in both motive and method.
