Hehe
If you look at Stargate Universe, the "fans" boycott watching the show and bash it all over the net, and it gets canned. It was a great show, better scripts and cast/acting, than the previous shows, a true gritty series. Now there is no new Stargate on the TV for the first time in years......
Another intelligent show I loved was Caprica, that's gone, with the similar fate of SGU, "fan" boycott and internet hate campaign. Remember Deadwood? They never even made the last season, due to poor viewer ratings, that was one of the best shows I have ever seen on TV!
So that's what I mean really, lots of really great shows disappear because nobody in the US watches them, or the fanbase actually try to force them off air?! Seems most peeps are too busy watching X Factor or crappy reality TV shows, and unfortunately it seems that trend is catching on here too, lets call it "dumb TV"
