As I've observed, most of the top movies on IMDB are quite old. This could be because these classics have had more time to gather reviews and ratings, solidifying their high-ranking positions. Also, they often represent breakthroughs in filmmaking or storytelling, setting benchmarks that resonate with viewers who appreciate their historic value. Moreover, nostalgia plays a significant role, as these movies remind us of a different time, sparking emotions that newer movies might not. Lastly, these movies have survived the test of time, proving their quality and enduring appeal.
