Not sure if it really counts because it was a manga/anime first but I've been playing some Naruto Ultimate Ninja Storm 3 recently and Naruto is easily the most boring character in the whole universe. There are characters who do not even speak who are more interesting than him.
The blonde girl from Resident Evil 4... I forgot her name. Most annoying protagonist/good character in any video game ever.
Kratos. Can't stand the guy, don't see why people like him. He's just an overall asshole.
