Why don't ppl stop at the top... Season 1-3 are amazing. Well written, good characters, amazing character development, amazing villains and plots. I've never been a fan of the animation, but it was tolerable. Then along come season 4... what a load of s...! Everything falls apart, new characters are boring, old characters have no development and are unnecessarily stupid. The plot is even boring and every episode feels like they are 4 hours long...
They should really have ended it at season 3. It seems like a new thing where ppl just have to milk everything good until it turns bad.
Oh yeah, and then they just felt the need for more diversity in season 4... once again a clear failure to add it so it makes sense. Please no more episodes!
