I don't rate shows based on any objective terms like quality, script, or anything else. I rate shows exclusively on my enjoyment of them, which is the only thing I'm truly qualified to quantify. If I had a blast watching it I might give it a 10. If it was a slog to get through I might give it a 5 or even less. If I found it personally offensive that I had to witness that, it might be a 4.

I don't rate what I don't finish. It's not fair, in my opinion. So I will likely never give away any 1s or 2s, because I don't think I'll ever be able to complete something that I find so bad.
