Alright, so I'll first give my opinions on all the New 52 movies so far. I though Son of Batman and JL war were both mediocre with Throne of Atlantis being just ok. I really liked this one though
First things first, it is not a direct adaptation of the Court of Owls but takes parts from it and tells a story about Damian and Bruce and does a pretty good job with it. The Court also came off as really creepy during the movie so they captured the tone right. Also the fight scenes were pretty badass and the overall mystery was solid. It made liberties from the source material but they weren't horrible divergences like in Son of Batman
If there's one thing I disliked, it's how the Court was done with so quickly. I really wanted to see Bruce face off against his psycho girlfriend but Talon was a well done villain so I'm not too bugged about it. Overall, much better than Son of Batman and pretty enjoyable overall 8/10
