Perhaps I would/might have liked that movie the first time I watched it, but there is no way I'm going to watch it again.
I would like to know which modal verb between would and might is the right one I have to choose for the sentence above, in order to exactly get my point across.
Here is a little bit of context, of course:
A friend of mine asks me if we want to see again a movie he knows I saw many years ago. He thinks that I enjoyed it that first time. Unfortunately (it can sound strange), I just don't remember whether I really enjoyed it or not (maybe, or maybe not), but by no means I want to see it again. Please, let me no if you need more details.
