A very enjoyable, but still, a hot mess. First 2/3 uncannily felt like Exodus - moving from A to B without any dramatic heft at all because ridiculously squashed for runtime - but definitely some very nice character moments. It improves over time and by the time you get to act 3 I was really into it, and the ending was great. Also to contribute to the hot mess - the Iron Man 2 syndrome, wasn't sure how I felt about that aspect but anyway...
Real standouts - Renner, Bettany and OLSEN (especially at the end). Banner/Natasha chemistry I really really liked. The character moments in general were fantastic, so much potential that I felt was unused really because of runtime constraints and overstuffing.
Also Ultron was pretty good, but yeah too fast origins I have to say...
Visually looks better than the first which is a plus, digging the look. Score wise...meh? Bits from first film really took me out, Elfman's stuff sounded really great though.
May need a rewatch, in the meantime 7/10
Bring on Civil War. TWS is probably still my favourite MCU film.
P.S. Trailers: Spy (both trailers), Pitch Perfect 2 theatrical, Minions theatrical, Jurassic World theatrical (the new one), Halo 5.
