How about Stop Watching instead of Wanting it Cancelled
There's a lot of tv shows I don't like, but I'm not going to be a self absorbed jerk and post that I want it cancelled. Complain about it. Fine. Say it sucks. Fine. But if it reaches a point of wanting it cancelled. Then stop watching it and move on.
You sound pompous when you suggest only shows YOU like should continue while anything YOU don't like should be off the air.
