This was a great movie. Not without a few flaws (I really disliked the short section with Harley and the President until she killed him), but overall I really enjoyed it. It was funny and well written, and I'd say its easily the best DC movie in a long, long time, beating even Shazam, Aquaman and the first WW for me (and I enjoyed those movies a lot).
Even as someone who liked the first movie as a decent action movie (while also saying that it was a horrible comic adaptation), this beats in in every way possible. This movie felt like everyone involved in making it both actually like comicbook movies in general and liked the Squad itself, and Gunn's style fit perfectly. The cast were all good, both returning and new (although I'm still just ok with Robbie as Harley, she'll never be anywhere near the best version of the character for me). I was totally not expecting the opening massacre, although I should have (I definitely thought that Savant would be a major character in the movie, they did a good job throwing me off with that). My favorite characters were probably a tie between Bloodsport and Peacemaker, but I liked all of them. Capaldi was great as expected, and it was amazing getting to see Starro. The President and general were just nothing characters, but that didn't really bother me.
My favorite scene was them killing all the people in the jungle, and then learning that they were all Rebels. I actually laughed out loud at their expressions and reactions to learning about that. A close second was Waller actually getting hit upside the head with a golf club for being such a giant asshole, it was nice to see her actually get a bit of punishment for being an ass, and I loved Bloodsport's way of getting himself and his friends away from Waller.
I'd love to see more of this, although I don't know if we'll be getting a direct sequel, and that Peacemaker show is definitely a must watch for me. I voted A
