Well...I was not a big Rob fan, but I do think he improved...also I have read the interviews with him after the first show..
1) the producers would NOT let him get a haircut thru all of the tapings..
2) he said himself that during flom1 he was really nervous bout the cameras..unlike the gals who got used to being filmed 24/7 in the mansion, rob stayed at a hotel, and came to the mansion for dates, and the cameras...so he did not get "used" to them very easily..
on flom 2, I guess his short stint of living at the mansion did make him a little less camera shy..
I also think he was pretty much in the dark till the end on flom 1...erin knew the score on flom2 :)
sooo...rob is NOT as bad as he seemed...maybe haha
