There are two things that really bother me about AR, and I think if they don't get rid of them next year, I'll probably give up on the series completely.
First, the begging for money. That should be prohibited. It's ridiculous, and especially when done in foreign countries, makes American television look pretty pathetic. If they want to have a non-elimination stop, then leave it at that -- a safe haven for the team that came in last that round. They already are at a disadvantage, starting out so late as compared to the other teams. If that's not enough, then get rid of non-elimination stops.
Second, the marital abuse. I think producers should assess substantial time penalties for any demeaning statements made from one partner to the other, and disqualify any team where there is an instance of physical contact that could conceivably be considered assault and battery, by the most liberal application of the concept. Barring that, go to a solo AR, instead of pairs.
