I sometimes watch Big Brother but a majority of the time they have a completely unlikable cast.
So my attitude toward Big Brother is, watch the first few episodes, and if they're all angry entitled douches like the average season, stop watching.
To me, the good seasons are season 2, season 3, All-star, and Dan's two seasons. Heck, last season I was shocked that the show was actually good. Season before last I turned off permanently the moment Dick walked in the door.
Most seasons are just a lot of shallow bitter 25 year old blondes crying and calling each other Satan. And then the year after the same shallow bitter 25 year old blondes dirty Amazing Race with their obnoxiously douchey presence.
