I actually liked the previous film more, it did have Damian in it, but I think this one was better, so I am giving it 5 stars.
I really liked John Constantine; he is a different kind of hero in my opinion, he's rude, he's kind, and he's smart, but most of all he's complex. I loved how they utilized Batman; he wasn't useless at all with a team of magic users, he used his cunning wit and prowess against new threats and he succeeded in his accomplishments. Batman is a badass and each writer that handles him should recognize that, like they did here, even though on paper he's out of his league, but the movie proves he's not; he's still Batman. Swamp Thing was cool and I liked how he was portrayed. Jason Blood and Etrigan were very fun and cool characters. I liked the voice acting for both of them. Zatanna was my favorite of the team, besides Batman, and she was really badass and awesome. The villains were cool as well, and I felt sorry for Richard a little. Deadman was fun too. I wasn't sure about the whole supernatural stuff before watching the movie, a little magic is fine, but I was worried about what a lot of magic would do for this DC universe, and I think it utilized and introduced it all well. Oh, and I was really happy that John Stewart was in this movie.
Sidenote, I read that Orm from Throne of Atlantis doesn't show up again, even though at the end of that movie Lex shows up to talk to him. I thought the scene meant that Orm and Lex would team up, but it went nowhere. What the heck.
Anyway, I liked the movie. The DCAMU has given me a lot of experience with good times. I recommend the whole universe. Please give it all a watch.
