I would probably handle this a little differently, treating the kids movies separately from other films.
You could tag the kids movies with a keyword such as "Kids Movies" and then create a new view which only displays files containing the keyword "Kids Movies"
Alternatively, you could create a separate user account for them, and tag the files with the username "Kids Account" (or whatever you choose)
That way you can set it up so that they only have access to files which are specifically tagged with that account, and nothing else, requiring a password to access the other files.

For the films in a series, I would handle it very differently.
I would create a new view with two levels. The top level would use:
TVInfo(SeriesDisplay)
TVInfo() Wiki This displays the
[series] information if it exists, or
[name] if not.
That way you can tag all your James Bond films with "James Bond" in the series field and they will all show up in that group.
The next view would be custom:
formatdate([Date,0],yyyyMMdd) [Name]
[Name, 1]
This will sort all items in a series by the release date, but only display the names.
There are images of how to set this up here:
