I saw it and really liked it! I'd give it a B+ overall. Much lighter in tone than the depressing Snyder movies. Lots of comic easter eggs in there. I think David and Rachel did a great job as Supes and Lois. Christopher Reeves is still the top Superman in my book (well for the first 2 movies, 3 and 4 were trash), but David did a great job. I really like Henry Cavill, but his material wasn't up to snuff. I thought Hoult was just OK as Lex Luthor, Gene Hackman remains the bar for the character.
Nathan Fillion was great in his role, and I like the other 2 members of the gang as well. Looking forward to see how they expand it. Krypto was awesome. There is a cameo at the end I won't spoil, but I didn't like the first interaction with that character (although my son told me it is somewhat comic accurate).
I didn't see the movie being political at all, and that is from someone who is center-right. I really think if you were offended by anything in that movie, you went in expecting to be offended and reached for something.
