It seems like the ability to "learn to like an artistic style" is akin to having a song grow on you or not really getting into a novel until you're half way through it. I'm sure it's true of all media - books, film, music, sculpture, and, yes, comics. The more complex or "deep" any of the above are, the more likely it is that something will need to take time for you to appreciate.
The first time I saw Demian 5's
"When I Am King" I didn't even get through the first chapter it seemed so boring and simple. Then I came back a few months later and read every single panel. When I first saw Eric Millikin and Casey Sorrow's
"FetusX" it just didn't do anything for me at all. Again, a few months later I found myself staying up allnight reading every single comic.
The same is true for print comic. I remeber the first Sandman I picked up seemed pretty cool (it was somewhere in the "fables & reflections" era i think) but it wasn't until Brief Lives that I started reading them every issue ...
Did I learn to like their artistic styles? Was it even their artistic styles that were keeping me away in the first place? Or did they just catch me on a bad day initially?
