Yeah I think there's more Logan bashing than there is Alec bashing in fics. Personally I love Alec (and I'm a Max/Alec shipper- don't hurt me!) But I think that comes from my dislike of Logan as a character. I much preferred him in season 1 and was almost a Max/Logan shipper but could never quite give up the hope that someone else would come along for Max. I just didn't feel like they had any chemistry, while the dynamic between Max and Alec was very entertaining.
Max was much more bitchy and aggressive in season 2 and I think my liking of Max/Alec was because I thought maybe his personality would bring out the not-so-angry-but-more-playful parts of Max's if they ever got together. While Logan just seemed to bring out the brooding and the sniping and the misery.
So yeah, that's why I love Alec, lol.
