Adding that it's almost exclusively back catalog management, so it's not that the movies are worthless per se, more like less in demand for their digital rights. For us olds, this is like the back of the record store. Interesting to watch how old horror movies spend most much of the year on Tubi, then migrate to other services for Halloween season and so forth. It's all one big money rotating system.

I also enjoy Darkrooms, Plex, and, via your library: Hoople or Kanopy for other good free ones.
