I always hear people talk about how great Death Note is so I tried watching it a few years ago and it just made me very uncomfortable the whole time. The show made sure to point out how great things are goin in the world when ever it could, like one point after the time skip it said that wars have stopped(???). At no point did it ever try making a point about how there could be a flaw in the justice system where someone innocent could be in jail and thus a casualty of the MC. Every non “criminal” he kills is someone who could potentially put a stop to his actions and thus comes off as as antagonists that the viewer Shouldn’t feel bad about dying. The whole thing feels like the author thinks that Light is actually a good guy.
I wouldn't say the politics in it are great, but L and especially the ending go pretty hard against Light's politics. The entire show is predicated on the battle of their ideas and wits, so for it to favour one side explicitly defeats that theme. I do wish L was more of a leftist-revolutionary instead of a status quo-pusher to Light's semi-fascism.
