ANYTHING above average is an acquired taste. Coffee.... sushi.... some of my favorite movies. How many things do you actually love right from the get go and hold dear for any length of time? New CDs are the same way. One of my favorite CDs in my trippin days of my early 1990's teen years was Beck's Mellow Gold. That album took a lot of listens before I really got it, before I really loved it. Same thing happens all the time. You hear a song and think "blah." Over time you hear it more and more and it grows on you and you love it.
I am fairly certain that anything beyond average is an acquired taste. Good movies like Donnie Darko, No Country for Old Men, Requiem for A Dream, Quills, 2001, Brazil, Blade Runner, that type of stuff. You enjoy more and more with each screening.
You may watch an action movie like X-men and enjoy it right out off the bat. But does your enjoyment grow with each viewing? No. Because it is average. Average things do not require an acquired taste. They are nothing special. I haven't listened in a few years, but I loved Neal Boortz radio show. That took some getting used to. I mildly enjoyed passing the time with Sean Hannity, but he was nothing special and no excitement ever grew as I listened to him further.
Get what I am saying? Anything above average really is an acquired taste.
