I watched the Global Warming Swindle show when it was on TV a while back... well, when I say watched, I was in my room, fannying about on the internet, but someone was watching the TV downstairs at a loud enough volume that I could hear it.
In general I thought it was a pretty poor documentary. It felt very dumbed down and had obviously set out to show that we weren\'t causing climate change, and thus that is what it did, without delving deep into the issues or attempting to counter further questions that their statements and \'bending\' of facts caused. I almost went into a long rant here about specific examples, but handily I clicked the link Avelorn posted and that shows the sort of thing I am talking about.
Any decent documentary, for me at least, begins with an open minded aproach to the subject matter (I realise complete impartiality is very unlikely but as much as possible) otherwise it is just a case of the director finding sources that put his point across. It should hold up a balanced window to the subject and ask questions of the viewer, not ram a message down their throat. This didn\'t feel that way and falls in along with things like Farenheight 911. They are less documentaries, more a visual representation of a self-imposing rant. If I want to see one of those I just have to come to the various online forums I\'m a member of and check out the posts there (yes, mine included)!
