I have read a couple of Terry Pratchetts books and I watched this show but I simply don't understand how anyone can find this funny. The jokes are worse than those that you get from a christmas cracker and just as old. Maybe it was funny when it was written but today it is just BAD. I was cringing at the humour and thought maybe a child might laugh but adults should be wanting something a bit more intellectual but according to all the 10's that this show has been given, they are peeing themselves at this rubbish. I guess I must be suffering from depression or something because this humour is SOOOO BADDD that I just don't get how anyone can laugh at loud or even mildly smirk. The story is not bad so I will at least give it 5 but as a comedy...a 1 would be generous.
