Just got back from seeing it and I can say I really enjoyed it. I'd say I like it about as much as the first one, though I can understand why some might like the first a little better. The character moments were great, especially Hawkeye's, and the action scenes were really good too. Not gonna lie, after I left the theater I was happily skipping to my car with the biggest smile on my face. Can't wait for the next one.
On a side note, really curious what the rumored extended version of the film is going to have.
