I really think that people need to take into perspective how much editing is done on these shows! They have 20+ hours of tape a day of every couple and they edit a few days down into a 45 minute show (allowing for commercials). For good TV, they have to edit the pairs into stereotypes. If you have watched past races, there are usually the same groups (older married couple, dating couple, best friends, ect.) and they edit the pairs to fit expectations we have for these pairs. We expect the older married couple to have a strong bond and patience with each other (Chip and Kim), we expect the dating couple to fight and argue (Colin and Christie), we expect the best friends to argue a bit, but be really cool about things (Linda and Karen). I wouldn't base all your opinions on a few edited minutes of television. Look at poor Jerry from Survivor. She is still feeling the repercussions of this.
I am glad Chip and Kim won. Yes, Kim didn't do the road blocks, but Chip was ok with that. It looked like Kim did a lot of things that don't make for "good" tv, such as handling the travel reservations at the airports and reading the maps. I didn't mind Colin and Christie that much either. They were extremely competitive people and they were in an extremely stressful and competitive situation for over a month. Of course the producers aren't going to show a lot of Colin's lighter moments, because that didn't fit his "character" on the show. We have all done/said things we shouldn't have when we are stressed and angry, the only difference is we don't have a camera for a national tv show following us around.
Ok, off my soap box now. Can't wait for Season 6! I have watched every season, and I love this show! Hopefully they can find a way to get this show on during the week, because I am never home on Saturday nights.
