If you read this blog you know I love Batman, he is my favourite comic book character and I certainly went through a phase where I enjoyed Teenage Mutant Ninja Turtles. I think the fact that they are still making comics, toys, and movies about TMNT is a testament that they are not a fad and are fun characters people still enjoying seeing and reading about. All that said I will admit it took me months to get around to watching this movie (free digital credit from Cineplex) but this past weekend I finally did.
Obviously, this is (mostly) more fun and light-hearted Batman story with the TMNT in tow. There are a few more serious moments, some intense violence but mostly I was laughing and smiling throughout the whole movie. It is a lesson for a lot of hard-core comic books fans, life is serious enough and it is great to watch something fun and not so serious (like that joker reference?).
The story here is fine but it mostly is just a service to get to the fight/action scenes which are well done and feature some great animation. Yes, I enjoyed watching Batman beat up all the TMNT, and of course, the fight (actually 2!) between Batman and Shredder was a blast. The writer wisely leaves out April O'Neil, Casey Jones, and even splinter from this story, there are already plenty of characters and it would have just slowed the story down.
I enjoyed this more than I thought it would. If you take it for what it is you will get plenty of laughs and some good excitement seeing these two franchises together in a movie. Be sure to stay through the credits for some nice surprises (I will just say it was a great twist on classic Batman comic book covers). I give it a solid 7.5 out of 10 and would recommend it to any Batman/TMNT fan who can take a joke. I would say please don't let small children watch this, ages 12+.
