I thought the episode was pretty good. I wish they advanced the arc a little bit more, I was hoping for some more April development and to find out at least SOMETHING new about the Krang or their motivations, instead we just get another random guy turning into another random mutant (which isn't the worst thing in the world) and some more fighting endless groups of Krang.
This would have been fine if we learned more about the Krang's story but it started to feel a little bit monotonous especially because they were fighting in the same dark city street setting and then their lair didn't even have a background it was just black (It could also just be monotonous to me because I watched the first 2 episodes 3 times).
Which makes me think: will we ever see daylight in this series? I hope so. I would love it if the Turtles use their trenchcoats from the OT in broad daylight and no one bats an eyelash I think the new series could potentially pull off some of that classic cartoon logic.
There were alot of funny moments in this ep, that seems to be one of the strongest aspects of the show. Next weeks ep looks good and to be a change from the patterns of these first 3.
