Because Mako is a jerk. He was in a relationship with Asami and cheated with Korra. When Asami found out, Mako just went and got mad at her and Bolin. Then even following the stereotypical jerk, he still gets the girl.

i like mako suck it pricks

Because he's a two-timing prick and a generic tough guy.
also his hair is stupid

hes an uptight hardass who pretty much dumped one of the hottest & richest characters on the show.

ANd money and hotness are the two most important things in the relationship. Not friendship and love. Definately not.

He's boring as **** .

I dont hate him, I like makorra

Because Borra.
He is a ******* powerful bender though.

I feel like they created bolin and his characteristics way too well, and he had too much screen time in the first episodes.

people are having hard time accepting the fact that he's just a comic relief character who doesn't really have any lines, maybe they do more with him in season 2 but honestly he wasn't that big of a character in Book 1, but people got too attached to him.

as for makorra/borra thing, it was heavily implied trought the whole season that they were gonna get together

>Implying I care about implications.
God damn it I hope Korra ends up with Bolin before the series ends.
She is so god damn shallow.

I actually thought Iroh was better. Blowing up airplanes left and right. Mako has had his ass handed to him quite a few times during the season

No doubt Iroh is the ******* man.
But Mako shot lightning while being bloodbent.
Lightning in and of itself is not easy.

It's actually more common than you may think, as there were many lightning benders in Make's workplace, not to mention that is probably a franchise spread around a bit, meaning more lightning benders.

true. The difficulty of shooting lightning while blood bent is probably high. But I'm sure he's a master of lightning anyways. After all, he one of his jobs was lightning bending a machine presumably to power it. Not sure if that'd be considered talent, skill, or both

Talent would be Toph, Skill would be Bumi.
