For me, I'd want the LotR tags to be under books, where I also nominated them. The movies have some significant differences (and the old cartoon is pretty wacky, and same goes for it), and I don't think including the Tolkien LotR "apocrypha" The History of Middle-earth in the tag is that necessary (also, those are books, too). I don't think most people know the radio plays by this point (including me), and afaik the video games are mostly too "young" to be considered for this exchange, anyway, or don't feature the same characters, or should have been nominated by themselves because they're so different (stuff like LotR: War of the Ring).
