Seen this twice now - opening night last thursday at midnight, so I was a little tired/easy to manipulate emotionally. And then on Tuesday.
Overall, entertaining film, with some great rollercoasters emotionally. Vibrant, awesome, laughs from start to finish, with more nuanced stuff inbetween.
However, I shouldnt have gone a second time so soon.
If I had to compare, this film is the Deadpool of the MCU - brilliant the first time, because it just hits note perfect. Once you've had the first taste though, you start looking for a bit more, and the cracks show a little.
I have to go with it not being overall as rewatchable as the first, but this film shouldnt be judged alone IMO. Very much like Raimi's Spiderman 1 and 2, both films make each other. They get better for being in sequence. First GotG is a solid foundation and the second fills in some emotional gaps and builds on almost everything positively.
That said, I could have done with a little less comedy at every turn, and would have liked to spend even more time with the characters at their truest, which is where the film goes at points.
Very enjoyable.
