Just downloaded the first episode of the UK edition of Big Brother. I can't express to you, the reader, how much funnier it is than the American version. Let me count the reasons:
1. Accents. Even just inside the UK, there are countless accents. Manchester, Liverpool, Wales, Scotland, etc. Each one is completely different. Very entertaining.
2. More than one gay person. In the American version of BB, I don't think there is any chance in hell they'd have more than one gay guy on at the same time. It may be becoming more acceptable to have gay relationships in drama shows, but that's scripted, written: It's artificial. I don't believe that they're ready to allow for the potential of the public seeing an actual gay relationship develop on national TV.
3. Swearing. As far as I can tell, it's pretty much uncensored. I've heard several of the major dirty words that aren't allowed on North American television, and there haven't been any bleeps yet.
If you have the means, I recommend checking it out for yourself.
