This show is evolving like any quality sitcom. It's getting funnier IMO.
However, it's also getting 'gayer' and by gayer I mean gross gay kind of gayer. At first the gays made me a little unconfortable, but they kept it funny gay so it was fine. At times it has been hilarious.
However, the last episode got sappy gay and they even kissed. I think the gay guys are funny, I don't care if people want to be gay, but I don't really want to see it.
So I hope this doesn't keep evolving into gayer realms. I hope they keep it funny, and stay away from gross gay.
