Over the years, two sites, Screen it! and Kids In Mind, have been very helpful to me in previewing movies — without actually having to watch them myself — when deciding whether or not I think that I want my children to watch them.
The Screen It! site is a little difficult to find one’s way around, and one might assume that it’s an just advertising site (it’s just not attractive or well laid out!), but it is well worth one’s while to spend some time figuring out how to find the reviews. They offer detailed content listing in many categories for every movie they review. Each category is then assigned a rating that summarizes the quantity and degree of the content. Here’s a link to the page that describes just what they do, and how to use it. Here’s another link that will take you to the page where you can type in the title of the movie you’re interested in reading about. You can use the site for free, or buy a membership and get added benefits.
The Kids In Mind site is a quite different and compliments Screen It! very well. Beside the title of each movie, the site gives a rating from one to ten in three categories: Sex/Nudity, Violence/Gore, and Profanity. They explain objectively, in detailed list form (from the beginning of the movie to the end), why a film rates high or low in a specific category. They do not recommend ages for viewers, or comment on artistic merit, but rather leave that up to parents based the parents’ own value system.
I particularly value these sites because neither of them are associated with any religious or other organisations.
