The best part of the film to me is that the boys are really likable. They each have their own unique personalities making for good laughs.
The big disappoint (and a spoiler) for me was that the whole movie is about Shredder being this dangerous bad guy. I was expecting a big battle with Shredder but in the end this did not happen. Instead, Shredder was easily tricked and defeated by another nemesis Krang. So, Turtles end up battling Krang to save the city.
I question why they made this PG-13. They really could have left the swear words out and the close ups on Meghan Fox. The violence or fighting is minimal and this is more about brotherhood than anything else. I think if I were a little boy I would have loved this film. As an adult, I felt the action is mild to moderate and the humans in the film are forgettable. I'll give it 3 stars for being a good kids film especially one that doesn't have a girl centered theme. I'm not saying girls won't enjoy this, I'm saying that it was nice to not see pink everywhere and soft fluffy animals for a change.
