There are generational divides in music. Punk was one. Rap was another. Metal a third. It's a point beyond which older listeners usually don't want to go, because it's just too noisy and abrasive on the other side.
I noticed the same thing happening with films the first and only time I saw The Matrix. I didn't understand it. This in itself is nothing new. What was new was my complete disinterest in gaining any understanding. I realised that the plot had probably been worked out in scrupulous detail so that it made sense in some way but I frankly couldn't be bothered to find out because I suspect I would have been underwhelmed by the conclusion. I decided to watch it scene by scene as if it was a collection of pop videos,
I felt the same about Source Code, which I watched this week. I feel that if it takes more than a minute to explain the premise of the film then I'm losing interest. This particularly applies in the science fiction idiom. If the hero has to ask lots of questions in order to establish whether he's alive or dead then there's a chance mere spectators like us won't be entirely sure either, which is bound to impair our enjoyment. I did enjoy it as a matter of fact but I probably only got about 25% of it.
