The difference between now and then is (based on Mulcahey's own interviews) he just didn't have a ton of time for Sonny period, unlike Guza.
I liked the story, even if there were a few rough edges in the plotting (Ava randomly mistaking Sonny's meds for sleeping pills). I think the plan was for her and Valentin to link up via their mutual interest and continue the scheme. I could've gone either way with keeping Ava or finally cutting her loose. I think she still has gas in the tank though, not unlike the Alex Olanov example I always cite from OLTL.
I think Mulcahey wrote some pretty good scenes for Jason and Carly, particularly the one where he explains his tattoo to her. But he was working at a disadvantage, namely the fact that Steve and Laura have no sexual heat unlike him and Sarah. I think this was a dream of Korte that was never going to work, and I think they have no clue what to do with Jason now. I think they had banked on putting him and Carly over and realized quickly it wasn't happening. Hence Brennan the dayplayer becoming ascendant.
No one said that.
