New format: I agree that having fewer weigh-ins was good, but I missed being able to see the percentage that each person lost, instead of just the total pounds.
Patrick did look hot, but you're right about the editing - it was clear neither of them would win.
And I agree about the marathon, too. For most of the contestants, it's just something to complete, they have no chance of winning. And running for that long is just boring, and probably not good for most of them. At least this year they actually pulled people off of the course, which it seems like they would have needed to do previously. I kind of like the idea of a triathlon (they could do the swimming part in a pool, if they're worried about lifeguarding), if they aren't too committed to the marathon idea.
The new twist is interesting. I can understand the one guy, who said something along the lines of "this isn't what I signed up for." I mean, they knew they would have to go to singles eventually, but at least at the beginning expected to have their teammate next to them encouraging them. I might be annoyed too, but I guess you really do have to expect anything at the ranch.
