Which is entirely up to them. Not everyone likes "cartoony" art. Not everyone likes more "realistic" art.
Yes, it does actually. You don't have to like everything. I'm sure there are plenty of things you never learned to appreciate.Art is subjective. That still doesn't excuse people from learning to appreciate different things. I used to a big fan of most of the OG Image guys but their limitations started to become more apparent when they didn't have an actual comic writer helping them a long.
And there are people that just don't like Nickelback. They've heard more than enough Nickelback to last a lifetime. Maybe they even once liked Nickelback...or liked that one song they did that one time... but now they've been overexposed to it...and they just can't listen to that shit anymore.For example, there are Nickleback fans and Nickleback haters. Then there are people who heard 10s of a Nickleback song and then decided they suck. The latter group should probably listen to a few song suggestions from a fan or acknowledge they don't have the time and profess their ignorance.
Nothing wrong with it at all. I've never said "No one should ever step outside their comfort zone". But there's also nothing wrong with looking at something and deciding "no, that's not for me". I'm sure you don't go watch every single movie that gets released...because you know what you like and what you don't like.Its the same for comics. I understand not having the time or money to read all you like but there's nothing wrong with trying stuff outside your comfort zone.
Maybe if the person read Squirrel Girl he would learn to appreciate that style of art. Maybe not. Doesn't change the fact that his initial reaction upon seeing it was that he did not like it. And there's nothing wrong with that.
