Missing Franchise Syndrome?

I don't know if this is really a problem, but I've noticed a few pages that look like they combine works in several different mediums because they're based on the same property. The three examples below are where I noticed this the most:

• Harry and His Bucket Full of Dinosaurs: A series of books that later got an Animated Adaptation. The page is in the Literature/ namespace, but most of the on-page examples refer exclusively to the adaptation. WesternAnimation.Harry And His Bucket Full Of Dinosaurs only redirects to the Literature page.
• The Odd Couple: A play that has been adapted into a movie (which later got a sequel), and four different TV series. Breaking it down further:
  • Both the film and its sequel have their own pages (potholed above)
  • One of the TV adaptations was the animated show The Oddball Couple which also has its own page
  • Another TV adaptation (The New Odd Couple, from 1982) doesn't even have a page
  • This leaves two other TV adaptations, one from 1970 and the other from 2015. The page for whole franchise is on the Theatre/ namespace, but most of the examples on the Theatre/ page refer to the 1970 adaptation.
  • We do have Series.The Odd Couple, but it refers exclusively to the 2015 series. Series.The Odd Couple 2015 redirects to the Series/ page, but Series.The Odd Couple 1970 redirects to the Theatre/ page.
• Pippi Longstocking: Another series of books that's been adapted into two different films, a live-action TV series, and an animated movie that was spun off into a TV series. None of these have their own pages, and the examples on the Literature/ page are partly made up of examples from each adaptation and the franchise in general.

I feel like something could be done about this (namely giving the latter two Franchise/ pages) but I don't know if anyone else sees this as a problem.
