Nathan Drake, he is just not funny to me which just leaves him as a chatter box that I would rather shut up. The main problem is that in Uncharted he was okay, in Uncharted 2 they just wanted a joke a minute and to make him never shut up. There was more jokes than plot and they weren't even funny. I like Drakes looks, I like characters that have a good style or design so I respect that part but his personality is so off I can't help but want to smash my ears in.
Kratos, I liked him because he was simple and cool. A big guy with a lot of revenge to be had but when god of war 3 came and he did nothing but rage and ruin any sentimentality anyone could have for him by killing good people, killing bad people, messing everything up and weirdly spending ages trying to help pandora only to let her go to have another smack at zeus that was the final straw. He became as 2D as marcus fenix but a lout louder.
Tidus, I just felt like he was talking in slow motion, mimicking Titanic in an awful way and annoyed me. He's the only FF character I hate too.
I know I only mentioned PS3 games so that may sound fanboyish but I have a lot of respect for some PS3 characters like sackboy, ethan mars, Alicia Melchiott etc, but Drake and Kratos are two characters that just don't do anything but repeat there stereotypes and do so in such a loud and focused way it grates.
