I'm trying to find all of the older seasons and watch them with the wife as we are running out of things to watch. I couldn't find them on any streaming platform other than the 2 seasons on netflix, so I downloaded 10 or so seasons through bittorrent.
Season 5 was the oldest I could find and was pretty lame except for the Miz going on a drunken rampage that probably would have gotten him booted these days since he was being verbally aggressive towards a couple of the girls.
Season 6 was better in terms of the challenges but it was a Boys vs Girls thing and by the end the girls were just unable to compete with the boys in most of the events. That season did have Puck though who managed to get married AND spit 20 feet onto the face of David from old school RW.
We're on Season 7 now which is the first Gauntlet. This is the first time they actually had an 1on1 elimination challenge to see who goes home. In the previous ones, the team just votes on whoever they want to get kicked off their own team, survivor style. It was really annoying because they were using a cumulative point system for the inner circle who decides the vote, and it ended up being the same 3-4 people every single time.
