Are these "tv-movie" keywords valid?

It would seem that these keywords are not valid, since they replicate information that can be easily searched via the database.

As a secondary reason, the keywords do not in any way involve the plots of the titles. (I realize that not all keywords involve plots, so this factor is not dispositive.)

And finally, many of these keywords (particularly the ones included at the bottom of the list) are poorly formatted because they refer to multiple things within the same keyword.

I really can't find any redeeming value in any of these keywords, but want to pose the question to the community:
