I know that reboot is a term often used by the media to mean a comeback of a franchise from scratch, but is my understanding correct of the terms:
Reboot: To start again from scratch, all previous continuity/canon is null and void.
Hard reboot: None of the previous continuity is canon any more - entirely new canon
Soft reboot: Some of the previous canon/characters/continuity carry over to the new movie, but not all. Partially new, partially related to previous continuity.
Remake: Re-making the original film, with minimal or no changes.
Re-imagining: Similar premise as the original but different in some ways (e.g. Christmas Carol films, The March Sisters at Christmas (a remake of Little Women, as I understand it).
Alternate continuity: It's canon, but the continuity is different from the original. Not quite the same as a spin-off. (Transformers is about the best example I can think of, apart from Marvel/DC Comics).
Is my understanding correct?
I am aware that many film series can be continuity-heavy, e.g. Freddy vs Jason, Captain America etc.
Just checking to ensure my understanding is correct.
