I'll be honest: so far, I hate the animation. And no, I am not a CGI hater. In fact, I usually have to defend CGI. But this just doesn't look that good. Transformers: Prime looks better, and I would hope that TMNT has a higher budget.
Also, the humor, so far, isn't my cup of tea at all.
Random quote (changes once in a while)
"I have sacrificed much to achieve peace. So too must a new generation sacrifice to maintain that peace. Responsibility! Duty! Honour! These are not mere virtues to which we must aspire! They are essential to every soldier, to every king!"
