So inconsistent

I tried Googling this but did not find anything. Why did they decide to go the 3D route in season five? I hated it. They did this with the movies and I thought it would be fine as long as they left the series alone but they had to go and experiment with that. I can't watch this season in full because of that. It just throws me off with the back and fourth.

Isn't it enough that the voice actors constantly change because they can't get the right channel for this show or whatever their problem with that is? This has to be the most inconsistent show I have ever seen.

The animation, the voice actors. The only thing they are consistent with is the whiny personalities of the girls when their S.O talks to another girl. Aren't they in their early twenties by now? I have noticed each site that has a bio of them only lists their age at the start of the series.
