Yeah, the romance elements for pretty much every character, are terribly done. The various relationships for Korra go nowhere, I mean, there is no functional difference in her when she's single, and dating Mako. When they break up, and then get back together, and then break up again, it's just like "well, I guess we're not dating now." "...yeah, I guess so." it has no impact on anything really. The water bender psychopath that pressgangs Bolin into being her husband, and then tries to kill him when he points out that he never fucking agreed to it, was just uncomfortable on every level. Just, really messy writing overall.I've tried to get into this show multiple times, but as soon as Mako and Bolin show up and that fucking love triangle starts going I just can't anymore. It's a shame too, cuz man this show looks so good - I really like Korra's design.
It's not the only example of bad writing in the show sadly, but it was one that was consistently terrible in my opinion.
