I went with the 8 point system because I think a lot of other ratings systems have redundant levels (like an 8/10 for great and a 9/10 for excellent). I feel that calling a film "great" or "excellent" or "outstanding" is basically saying the the same thing. I suppose I could have had a 0 for a film with no redeeming features. On the other hand the 4-star rating system seems too basic.
