They did overdo his crazy-ness a bit at times, but they overdid it with other things too. They were very heavy handed on how Michael is a scumbag to the point where the dialogue doesn't seem natural and just sounds like the writer telling you what the point was.
I still like Trevor as a character. He can be complex at times too. He has his mother issues especially when she appears (or "appears"), he actually gets shamed by the one guy after Trevor works for the redneck ICE knockoff.

That did suck. Rockstar were very hard on Johnny and The Lost in general in V. Trevor's scene with Terry and Clay afterwards is still funny though.
