How good is your movie memory?

Pretty bad too! I also remember casts and crews (at age 12 I knew people like Bob Murawski and Bill Pope because I was always studying the credits of films that I loved), but I can never remember quotes, for instance. I forget plot events too quite often. What I do remember is the feeling I had watching the movies, but rarely hard details of the story and so on.

Pretty poor across the board, like you and Jango I don't forget how I feel and my opinion on the film but certain plot-lines, quotes etc just go out of my head unless its something I've seen a few times.

I'm also pretty bad at remembering scores, I may know at the time whether I liked them but music in general just gets forgotten with me. Usually that's how I compile my score line-ups, if I can still remember it a few days after the film it must have had something going for it.

It's pretty good for movies I enjoy.

It depends on how many times I've seen the movie and the "factors", like shock value, major twists, entertainment value, emo value etc etc which can make me remember intricate details of even the films I've seen once and may or may not plan to see again. Requiem, for one, is a film I can really remember each scene of, some better or worse than others.
But some films, which bore me to death, are ones which I forget I ever even whatched. Any Avengers film would be a good example of this.

So, my memory is real hit if I liked the film nuff.

I started watching films on a regular basis 4 years ago and I can pretty much recall plot details and cast/crew and memorable imagery of all the films I've watched

It was really good until I suffered a concussion last year. *sigh*

Depends on what we're talking about. I never record my favorites and prefer to make them based on what I remember at the moment. I can remember what I've seen, though.

If I've only seen a movie once, I'm always amazed how little I remember about it years later, even if I loved it. I'll remember vague moments, or just remember liking a particular scene without having any idea what the context was. I always have to go on YouTube or Wikipedia to refresh my memory on things.

Like I'll go to Letterboxd and pick a random page and a random movie. Hunger Games: Catching Fire. Saw it in a theater, paid attention to the whole thing, really liked it, haven't seen a thing from it since...I remember a chase scene in the woods and the old lady dies and her friend is the new young guy, and he was shouting after her crying. And I remember the end where Katniss gets saved from something and lifted into the air and PSH is in a room, and there was the big closeup of her face getting mad. Because the game had been rigged or something. And Jeffrey Wright was in it and there was some stuff where they were hanging out on the water. I can't even remember what the setup was, it was like teams? And there was some stuff about Katniss and Peeta being famous at the beginning. And Jena Malone flashed everybody in an elevator, I think. And I remember it being a little more dynamically directed than the first one in general.

I’m usually very good with cast & crew and the year of release (plus some additional facts) but I’ve always been terrible with dialogue.

Very good.

The fact that I can watch all these horror movies and still remember minute details that annoyed the shit out of me from each one is quite impressive if I do say so myself.

However, since so many of these movies share very similar titles, I do sometimes need to look it up and then go "ah, it was that one... yeah, it sucked."
