I think he's a little harsh with Psylocke, like, I said, but I don't think Remender tears any of those characters down. He reigns them and builds up some of them. I think the thing with that team is they're starting to lose their morality and without that, they're just killers. Logan and Betsy have been at it for a while, so it makes sense that they get it the hardest.
The whole thing is this huge, great redemption story for Fantomex. I love how every major thing that happens stems from his actions at the end of the first arc. He fucked up, he knows it, and he does his best to make it right.
Deadpool is like Renender's secret weapon. He completely subverts your expectations by making him the groups moral compass. He jokes and he'll get his hands dirty, but there's an integrity at his core that comes out when it's needed most.
It's funny you say Renender probably hates the 90s. When I finished Uncanny Avengers and posted about that, Tyrant Rave said it seemed like Remender enjoyed Avengers stories and that UA was in the spirit of Kurt Busiek's run.
