Liking or disliking films is, more often than not, independent of intelligence.

Just because you now enjoy films doesn't necessarily mean your intelligence has changed. It's more likely to mean that your personality has changed. Remember that there are almost certainly many people that are smarter than you whom absolutely love films.

Please don't be the guy in the room who thinks that they're really smart because they have different/non-existent consumption habits than other people. This is dumb social signalling because others will think you are being pretentious.

You seem to have some kind of hang-up about being seen as being smart by other people...
