I mean. Is it possible? Hey Zeroq give me a good gangster flick please?

How will you know what i have seen and what I haven’t yet? How will you know what movies I like? Are there even good gangster flicks i would enjoy and haven’t seen yet?

The way the problem is phrased it sounds like your dream recommender has two properties: “it doesn’t receive any other information than what is in the prompt” and “it always recommends a movie you haven’t seen and will enjoy”. Those together are what makes your dream recommendation engine impossible. If you relax those then of course it is possible. That’s just a recommendation engine.
