salina70/MovieVibe ? reverse-engineered prompt

Build me a full stack movie recommendation app called MovieVibe.

I want users to be able to sign up, log in, and tell the app what kinds of movies they like, then get movie suggestions that match their interests. Make it feel modern and easy to use, with a clean home page, a place to edit preferences, and a results page that shows recommended movies with posters, titles, and a short reason for each suggestion.

Use a simple MERN setup with a frontend and backend, and add the AI or ML part in a practical way so the recommendations are personalized instead of random. If you need current docs or a movie data source, look them up online and use the best simple option. Also add basic error handling, loading states, and a nice responsive design so it works well on mobile too.

Keep the app polished enough that I can run it locally and demo it as a semester project.
