I've noticed a lot of threads referring to movies as "classics" and I wonder what criteria a film needs to meet to be considered one. What piques my interest is a series of unrelated posts that apply "classic" status to movies that were, at best, mediocre (both critical and box office flops). I'm starting to believe the term "classic" is used simply to describe films that the viewer liked at one time, is still fond of, and wants others to like as well. The word seems to have no relation to artistic merit, box office success or critical praise--it simply suggests likeability, as in "Dude, that movie rocks!" Thoughts?
