Did I miss something with him?

I just finished reading Elantris last night, and while i agree it was somewhat weaker than other cosmere books, it was pretty enjoyable! I really liked Sarene and Raoden as characters, too!

But, i've been so many people praising Hrathen's character, even before finishing the book, that i was expecting something more from him. But, for like, 90% of the book, i hated him, and his chapters just felt like something i had to get through to keep reading the stuff i liked. And yeah, his redemption was nice, but for me, it felt like too little, too late, and then he died pretty quickly afterwards, so not much time to like this new Hrathen.

Of course, this is not a dig at anyone that likes him, i'm just curious, because seeing so many people not only liking him so much, but saying he's a "top 5 cosmere character" when for me he's more like bottom 5 povs, i can't help but wonder... Have I missed anything with him? Is there something more to his character that could've made me love him and I just didn't get it? Please, I'd love to read your opinions!
