The value in the purchase is definitely the back catalog. Amazon now owns the entirety of MGM's movies, meaning anyone who wants to have them on their streaming service (Netflix, Hulu, et al) now has to cut a deal with Amazon for licensing. Even if they do cut a deal, Amazon still has those movies as yet another draw for Prime Video fodder, or to potentially stick on IMDBtv to be ad-supported.
