Saw this last night. It was awesome!
Very sympathetic villain, too. I actually really enjoy villains more this way versus just simply outright evil.
I could understand sympathetic if he didn't murder his own allies to get what he wanted, and I don't mean Klaue. I mean the lady who was explicitly in love with him and working with him because of that.
Also his plot was basically transferrence of vengeance from T'chaka to the rest of the world, and his goal was to repeat what he saw as the sins of the rest of the world but with him on top. You can understand why he's a broken man, but I don't think he's quite as understandable as Magneto (who despite the meme, is not right. Has some valid points mind, but isn't right) given Magneto's trauma was personally experience, repeated and directly because of his heritages, feeling that his tactics were the only way to ensure survival for his kind.
This Erik chose the tactics he did specifically because he wanted to destabilize the world, to fuck it over, not realizing that those would very quickly lead to even more death and destruction for those he saw as his people, especially those in Wakanda.
I also don't understand why T'challa didn't tell his best friend that Killmonger was the one who rescued Klaue, there was plenty of time both before and after he showed up.
Granted, this gets into the common superhero problem of "what is telephone" but it could have stopped him from turning turncoat in the final battle, though he was always a bit warmongery.
I did like what they did with Klaw and Erik Killmonger, given that a being of literally pure sound and a man with the last name Killmonger were just a smidge too silly for the MCU's earth.
And as for what Genre they were pulling from this time? James Bond films with a bit of shakespeare.
Not my favorite nor I think the best MCU film, but very good overall.
