I’m more disturbed by Batman Forever getting a 5/10. Granted, that is a solid F, but I don’t understand why anyone finds much redeeming quality in it.
I don’t think stars and letter grades should be considered equivalent. There’s nothing lower than F, so I don’t think it makes sense to give a 1/10 and a 5/10 the same weight.
This is why I stopped using number grades, because I can’t really get over 7/10 = 70% = C-.
