I watched all three seasons. Why? I love John Cameron Mitchell. No other reason. The show is so heavy handed in how it deals with the issues surrounding the main characters weight, it was impossible to do anything but groan and roll my eyes many points during the show. It's as if it was written by a skinny person having to make up what they think it's like to be fat.
I would give it 1.5 if I could. It wasn't the worst thing I've ever seen but I'm not surprised it got cancelled. And it leaves season three on a cliffhanger so, imo don't bother.
