Is anyone else glad the TMNT and villains don't have "power levels?"

One of the best thing about TMNT is the characters never actually "get stronger" over the course of each series (for the most part), and all the characters stay at the same relative strength over the series. It isn't like anime where the characters "power up" or gain new abilities over the series where they couldn't beat a villain before.

Same thing with the villains, the villains all stay at the same relative strength (sometimes Shredder is too strong for the Turtles at first, but the Turtles don't "power up" to beat him, same with Shredder), and they just do basic martial arts training with Splinter. When new villains show up they aren't more powerful than older villains. It's all relative.

Sure there's some exceptions, but for the most part the Turtles and the villains do not have power levels over each cartoon and comic series.
