IMO What you are after is not curation per se (Personally, I use this list [0] to curate good old movies myself)
What you are seeking is different: (very) limiting choice (=rewatch classics / compel us) and the whole experience ("just a playlist. Where's the joy?")
IMO there is no tech solution to this. The digital is about abundance. artificially creating scarcity seems esthetical to me.
Maybe you should make it more of a social experience? invite friends/family/community for a special night on a home cinema ? or in some Revival house [1] ?
