Liked that it was a little based on the horror movie "the fly", but the built up to Mutant April, was just so damn teaching and so even more dissapointing. I knew something would be bad if they make April a bigger role than just the human friend.
I couldn't be disappointed. It was established many episodes ago that she's immune. That stupid serum was made from her blood, how turtles could forget that? Add disgusting view of Baxter as fly, curing April's father with one damn drop and some smaller stupid things and we have worst episode ever. I'm going to check first TMNT cartoon, I just hope it was better.
I seen it too (got curious, after Critic talked about them), but it was only five episodes. I can count at least four show that I didn't liked at first, but got much better later (Secret Saturdays, Ben 10 Alien Force, Young Justice and My Little Pony).
Besides, I already watched second show, so I can as well fill the last gap.
