So... I saw it.
I, uh... Ok. It had some good parts. On the whole, I was bored, though. I can't stand the whole 'I love you , but I can't have you, and I mess up, but YOU mess up and on and on and ON' crap. Which is what the whole second movie was, and a good chunk of this one.
Personally, I found the Sandman a much more compelling 'bad guy' (if he can be called that) than anything. Though, I'm glad Venom wasn't 'Venom' for very long (as I was never a fan of the character).
J. Jonah was a joy, though, heh. As always. And there were a few good spots...
Crowd wasn't in it, though. I have to say, each time I saw TMNT the crowd was way more into that they were this (though it could have been this particular crowd, also). The kids in front of us (two of them around 10 years old, some younger) actually fell asleep a little more than halfway through.
I'd see it again, to see if I could get a better 'feel' on it. Maybe I was tired. Either way, it had it's good points... Every so often, heh.
