Even when they had Adam Sessler, x-play just became way too boring. I recall the best episodes of x-play were the ones in which Adam made these comedic sketches, or when they added a large amount of humor to their reviews. The past few years I didn't even like watching the show, x-play and Adam took themselves way too seriously.
As for AOTS, I loved it and I would always try to see it when I got home, but the overall quality it declined a bit when they hired Candance Bailey in Munn's place (I would have preferred Underwood or Alison Haislip). The only reason I watched it was because Kevin was hilarious (and to see Sarah Underwood). But after Kevin left, I have only seen DVDuesday and gadget pron clips, and from what I have seen all the guest hosts were terrible, so I doubt they would have survived without Kevin anyway.
