Honestly, I don't think it does. For your last point on your death note post. There's certain context and spoiler reasons for why I think so but it could also be just my interpretation. And in all honesty, it's not a completely awful movie. By no means is it good, it has lots of flaws that don't pertain to the death note reasons. However, it's meant to be completely desperate from the original series. Not even in like a reimagining sense, it's supposed to be taken as it's own thing. 1/2
and honestly if you're capable of separating the original death note canon from this movie, it's not terrible. Not great, but not terrible. The last 15-20 minutes are actually REALLY good. But that doesn't make up for the flaws in the rest of the movie. The director also said that this movie is to be the first of a trilogy, which if you do finish it, will make the move make a lot more sense. However the trilogy isn't confirmed for being made, but it's something they're trying for.
if they wanted it to be a separate thing, why didn’t they change the character names. they changed everything else about the characters, whats the point of still calling them light or L or misa. just have it exist in the same universe as the original death note or make something new. the only reason they’d have for continuing to use the death note character names is for brand recognition to attract fans, but then they shit on it all and make the fans hate it
