2) Jacob Portman from the Miss Peregrine's Peculiar Children series. Like Harry Potter, Jacob's something of a nothing-character, someone who you put your own mind into, but I think he's even more nothing than Harry. Just didn't work for me.
3) Dash from Dash and LIly's Book of Dares. I put this book down specifically because I couldn't handle how pretentious Dash was. It was like, no.
5) Sara Wharton from Tease. This is another book I put down specifically because of the main character. You're supposed to dislike Sara, it's supposed to be unpleasant to look at the story from inside her head, but I just couldn't handle it.
6) Aspen Leger of The Selection trilogy. Like Gale, Aspen was the corner of the love triangle that I just didn't feel. It was like, please go away and leave my America with my Maxon, thank you. You're boring.
7) All of the characters in Little Women except Beth. They just all really, really annoy me. Sorry.
8) Adam Parrish from The Raven Cycle. This is sort of another "love triangle corner" disconnect, but in general, I just find Adam to be a bit of a "meh" character. I appreciate his importance to the books and to the friend group, but... meh.
9) John Smith (Number Four) and a lot of the others from the Pittacus Lore series. I don't like this series. Why do I keep reading it? I don't know! There are some absolutely fantastic characters, but the problem is, they get the least page-time. The characters who get the most focus, like John, are the ones I find boring and annoying and can't connect with.
10) Eragon from The Inheritance Cycle. Like.... just... boring? He's another nothing-character, which can work sort of depending on how invested you personally are in the world and the plot, but it's hard to deal with this guy sometimes.
