Near

I agree with most of the comments below.  Near, on his own, isn't that bad, but due to the unmistakable similarities to L and pratically being a copy, but a copy that is lacking compared to L, naturally, I dislike this character.  He doesn't contribute that much, like, all he does is sit and play with his toys, coming to conclusions due to pure assumptions (unlike L, who actually had plausible reasons to suspect Light) and/or letting someone else do majority the work.  His attitude, posture and personality is way to similar to L, it could be because of the orphanage, but we see Mello, who was also raised in these conditions, develop a much more unique personality. 

Hey you ittle piss baby

You think your so fucking cool huh

You think youre so fucking tough

i don't exactly hate this guy, what I hate is he's introduced to the anime. The fight between the 'justice' have always been L and KIRA, they should've ended it with L defeating KIRA or KIRA defeating L. 

Ok, I haven't read the manga yet so I'm not fond of Near for being a cheap L rip-off. L's my fav so it hurts when they tried to replace him so easily. I'm sure Near is a unique and interesting character with epic character development in the manga.

I don't understand why everyone hates Near. I loved L, and Near is... eh. I think if I'd seen Near in a different context (maybe even a different show?) and he got more character development, I would have really loved him. As it is with his role in Death Note and his constantly being compared to L, he's kinda eh/plain/unexciting. I'm more neutral towards him and kind of sad that I didn't get to see this character in a different context.
