I don't rate shows, as I'm not found of arbitrary numbers. One person might view 7/10 to be average and thus rate a show they found to be mediocre that verry same rating. However, another person might veiw 5/10 as beng average and 7/10 as being pretty good. so there's already a disconnect there, the same number means completely different things for two people.
And then there's the fact that a number is just a conclusion, it doesn't cover why the person did or didn't like it, what the person's stadards were or if it's something you would enjoy. If you wish to know what I thought of a show, ask. Use your words fool!
