Spin-Offs We Don't Need

[DekuNut]

These days, we're getting spinoffs and sequels about a lot of things, from The Rock in Fast and the Furious to a textbook in Harry Potter. Some of these are interesting, like Rogue One; others are not.
What Spin-Offs or side stories do we not need told? This can be books, video games, movies, whatever. Be as serious or not as you want with these.
