I totally agree with Touching the void - loved this one, has to be one of the best docs I’ve ever seen, also liked supersize me too, and have seen the catfish tv show, some of the stories on there are so odd
As promised, in return for all your suggestions here are some others I like, in case any of you are similar to me in your tastes! I haven’t checked all the links work though, but hopefully if not a quick google will find them. Apologies that it's a mammoth post....
