So I might get a lot of criticism for this but...
The new show looks stupid.

My main thing is that THEY'RE ALL DIFFERENT SPECIES OF TURTLES! How are they supposed to be brothers when they're not all the same species!? It doesn't matter what species they are as long as they're the same!

Second, WHY IS RAPH THE LEADER? It's always been Leo and they've always butted heads on occasion but in the end they still care about each other a lot! Also, his weapons are batons. HE'S ALWAYS HAD SAIS!!!!!

Next, Master Splinter looks ugly. Just the way they designed him bugs me.

As for April, I like how they made her African American. I understand why and frankly, I don't mind. However, what bugs me about her is her outfit.

Out of all of them, Mikey's probably the best one as far as personality goes.
