There are some movies that you just never get around to seeing and they can remain an unknown quantity for many a year. If any of these films were a big event at the time, or have become a major part of pop culture, then catching up with them can presents its own set of problems. For example the status of some cinematic classics or cult movies inevitably raises expectations, which then may be hard to meet. Then there can also be pressure not to fly in the face of popular consensus, leaving the viewer obliged to like a film or find merit in some way. I had this experience myself recently when I finally caught up with Spaceballs.
