Mikey and Don series

[Refractive Reflections]

It's kind of similar to 2K3 in a way where they are giving the deeper storylines to Leo (i.e. "Follow the Leader", "Fungus Humungous"), making Mikey's stupidity as the focus of the humor (as shown in "Pizza Face" and "The Mutation Situation") and giving him a few redeeming episodes ("Parasitica" and "Mikey Gets Shellacne") to not make him be seen as a complete burden/annoyance, and giving Raph's short-temper (being annoyed at Mikey and Casey), and clashes against his cocky ego for humor sake too much attention (i.e. his fear of bugs).

Donnie was getting some character growth in focusing his concern toward Metalhead and Timothy, but that's been obscured and heavily overshadowed by the bothersome and directionless April crush.

There are episodes that seem to allude to a good direction of where the series could expand the Turtles' characters, but the series regresses back constantly from those possibilities. The unfortunate thing in this current situation is that, there are only two main storylines occurring in this show (the Kraang and Shredder), and since April and Karai are involved with them respectively, Donnie and Leo seem to be highlighted by "default" because of their crushes rather than something more substantial.
