I actively don't think much of Avengers 2. I don't hate it or anything but it really is something that completely left my mind as soon as I left the theater. This is in fairly stark contrast to Avengers 1, which had a lot of standout scenes and a very charismatic villain. There isn't much new being explored or much meaningful character development in Avengers 2, and I found the action to be really uninspiring, incomprehensible, or kind of boring (again, in contrast with Avengers 1 and other Marvel films). I think a big part of my apathy is that I had seen basically this exact movie in the past but done better. My thing is that the Marvel machine can make hundreds of movies of this quality and they're going to be really inconsequential seeming to me if no progression is being made, and that's what it felt like for me. Avengers 2 doesn't set anything very interesting up, it doesn't do anything new, it doesn't develop character relationships well (Hulk x Black Widow makes little sense and is really ineffective), and it does a poor job of having particularly meaningful stakes (knowing about Phase 3 really takes the sails out of most of the tension this movie has). Ultron has some presence but not much about him or the plan make sense. I didn't have an emotional reaction towards the end, because of what Cid said (it's a really calculated move in the grander scheme of things), plus the nothing characterization.
There are things to like (party scenes were good) and I don't begrudge anyone's enjoyment of it, but it never came together even as a piece of pure entertainment for me.
I echo Cid, Fury Road is unlike anything I've seen recently. I think it hits on everything it sets out to do extremely well and it's incredibly visually striking. It was also pretty excellent even if you only want to be entertained.
