Since you mention it, I think "pile" is a good description of Rogue One. While its true that movies like this Solo prequel and Rogue One are just garbage piled up on top of the decaying carcasses of the prequels, the Ewok made for TV movies, and other "Extended Universe" nonsense, I agree with you that they are by and large forgettable pieces of garbage, or "piles" as you so appropriately refer to them. So at least they don't linger in your consciousness like the taste of onion. More analogous to Taco Bell, which goes in and comes right out of your system.
Rogue One and Han Solo prequel--the Taco Bells of geek movies.
