I find that with any sort of comedy, you wind up...internalizing the formula. You get used to it, and you can almost replicate it yourself. You know the equation/formula behind the graph, as it were. I don't laugh out loud at 30 rock anymore; I used to.
But yeah, sometimes I worry that Croshaw is getting bored with ZP, treating it as a chore. As a fan of things, its something I worry about; that the person writing the stuff I enjoy isn't having fun, and resents the fans that keep them doing it.
I still enjoy ZP, but I never seem to laugh out loud anymore, and I was rather disappointed with the Borderlands review. I often find the full-length articles more interesting and insightful.
Most recent one was funny though.
Sometimes I miss those little experimental things tacked on to the videos that used to happen occasionally.
