I'm trying to find a simple way to keep track of movie releases that I'm interested in. Is there an app or website where I can just type in the movie name and get notified when it's available?

I've seen some posts mentioning setting up RSS feeds, but that seems a bit complicated for what I need. Ideally, I want something where I can just hit "get notified" and then receive an email or notification when the movie is released.

Any recommendations? Thanks!

(Not just when they are released in cinema but as 1080 or 4k)
