Hi Missy, There are a bunch of good ones, but I generally use link. Their reviews are quite thorough and very detailed so you know exactly what kinds of potentially kid-unfriendly bits are in a given film.

I'll probably go ahead and add this link to this spot's link list.

Yeah, I've used that site before and it has a lot of really good information like scenes that might be too much for kids to handle. Good suggestion Papa.
