S1 got hate watched by alot of people who wanted to see the train wreck. Their viewing figures were not impressive, but inflated due to people wanting to see "if it got better".
S2 could faceplant hard and S3 would likely get pulled, but that remains to be seen. I don't know anyone who actually plans on watching S2, and after the ending of S1 I find it hard to believe too many people are going to give it a shot, but we shall see.
