my comic-appreciation-thing went from garfield to calvin&hobbes to maakies to achewood.
Similarly I went from liking Peanuts and Garfield when I was a kid (partly because that's what I had access to from my parents or brother) to Calvin & Hobbes, which I do still like (along with Peanuts, can't really stop liking Peanuts...) and now to Achewood, Penny-Arcade and Goats which are pretty much the only strips I read anymore (as I am reading comics still - if you haven't started reading Whedon's Astonishing X-Men, then, well... yea!).
so i've been going through a bunch of boxes of pack-ratted crap/really-important-things, and i found my old garfield books. i would suggest that jim davis' work _is_ funny, but that the humor loses much after considerable exposure.
i loved peanuts as a child, and then i didn't like it as i grew "older". now that i'm growing older-older, i find i appreciate parts of it that i didn't even realize existed upon first exposure.
i loved goats when i first found it, read the archive that existed at the time, but just don't find it compelling enough to read daily. i'll go back and "catch up" every once in awhile, but i don't feel as though i'd be missing anything if i didn't.
i find PA to be editorial, and in that way while it is always the same old same old, it's at least the same old same old applied to new things.
i generally find myself compelled with figuring out what is going on with the characters, and once i find i "know" them, i grow bored with them, i guess. which is why achewood has such a hook in me, since character insights are constantly doled out in tiny yet satisfying increments. plus onstadt's ability to generate so many distinct voices.
