You cannot attribute their success simply to repeated TV runs though. Some films are just not that appealing for the cinema, more art than entertainment, and slowly convert each viewer into a fan until it joins the collective consciousness as a classic. It's a story that all of these have in common - some level of critical acclaim before release, flops at the cinemas, slowly builds up a reputation.

I'm arguing that repeated TV runs allowed audiences and critics to deeply ponder and appreciate these films. Sustained attention over time, which caused a re-evaluation of their artistic merit.
Saw "Saving Arizona" right after losing my girlfriend. Saw every problem they had as tragic instead of comedy. Didn't like the movie. Some relatively short time later. Saw it again. I was my favorite movie for years after.
