I have to agree with you about Luke. He's grating on me. Favorite team so far is Gay Son/Dad and I'm liking Cara and Jamie. Keisha and Jen have not made much of an impression yet, I'm on the fence about Tammy and Victor and the other two teams seem to be struggling.

As for Survivor, I'm liking the twists of the cross tribe alliance (and the fact that one of the group isn't fully committed). Rooting for Taj at the moment but this is subject to change.
