Welcome aboard, Cap’n Crunchy! I’ve been hooked since I watched the finale of the first season. Highly addictive stuff, but very enjoyable.
As David B notes, they’re not available on video. I’d watch S1 myself, since I missed almost all of it. If you happen to find someone who has them on video, I’d recommend S2 (Australia) and S6 (Amazon) as the best ones to watch start-to-finish. Frankly, though, I liked 'em all.
If you really want to know, the winners are in the spoiler box below: [spoiler]S2: Australian Outback was won by a middle-aged woman named Tina, who beat out young Texan Colby after Colby stupidly chose to take his friend Tina to the finals instead of the very unpopular Keith.
S3: Africa was won pretty handily by Ethan, a young professional soccer player with basically no personality. Fan favorite Lex, a much more colorful character, missed out on the finals when he got sick in the last couple days.
S4: Marquesas was won by Vecepia, a middle-aged woman who is quite sure that Jesus forgives her for breaking her agreement with fan favorite Kathy, who finished third. Worst finale ever.
S5: Thailand was won by soft-core porn actor Brian, who appears to be quite the jerk in real life, but who kept a lid on it during the game and did a great job of playing his teammates for fools.
S6: Amazon was won by bitchy model Jenna, who stomped weirdo Matt in the final vote. Again, the fan favorite placed third. This time, it was a guy named Rob, who did an amazing job making and breaking alliances seemingly at will. Rob was also the most amusing contestant ever, with any number of priceless observations and one-liners. [/spoiler]If this season holds your interest, you will be able to see a number of the previous contestants next spring, since the next series has been announced as an “all-star” version mixing and matching contestants from previous seasons.
