Assigning a Rating to a Movie that's "not for me"

Tonight I just watched "Food Truck" and "She Dances". I was kind of bored in each of them, for different reasons. But I know there's people out there who would really like each of these movies... they're just not for me.

"Food Truck" is from Thailand. To me it seemed sappy and a little cliche.... but I could see it being popular in Thailand. "She Dances" would probably be appealing to parents of teenage kids... which isn't me.

So I don't really feel like these aren't good movies, they're just not meant for me. I'm not sure how to rate something like that.
