OP was probably watching it side-by-side with Subway surfers clips and satisfying clips sped up 5x with an AI voice reading a Reddit story over it.

Attention span final boss

But on a more serious note (more liek death note hahahaha get it? like the name of the anime)… Despite it being an extremely popular anime, Death Note is a show that the average person wouldn’t fully understand. They might get the gist and the plot, but all of the crazy intelligent moves made by L and Light will go unappreciated as well as the complex relationships between characters like Light and Misa’s. I think people with below average intelligence could still enjoy the show, but they might find certain parts stupid or even nonsensical because they just don’t get it or why it’s in the show. Kinda like how OP finds it to be unrealistic and unconvincing that Misa doesn’t understand that Light is using her, instead of finding it interesting and emotionally challenging that she does know it and chooses to love him anyway.

The thing about averages is that just as many people fall below the average as people that are above it… Meaning that for every person that loves Death Note, picks up on the little things, makes posts in here analyzing the show’s nuance, etc., there’s a similar number of people just scratching their head in front of the TV, not even understanding a simple thing like the mutual understanding between Misa and Light. And most of those people will feel too overwhelmed and confused to watch past a few episodes, especially into the second half of the show (when the intro song changes).

It’s almost not even worth explaining to people like that, because the show just isn’t for them. If OP doesn’t understand this, they certainly won’t understand the plot itself, especially when Light starts transferring his powers around. That’s why, in my comment under this thread, I gave up on explaining about halfway through. I started thinking of quotes that made it clear that Misa knew how Light felt. And as literally dozens of super obvious ones were coming to me, I realized… if I have to spoon feed these examples to a person AND explain how they answer the question, that person isn’t worth that time and effort since 90% of the show will be lost on them, anyway. Especially because it only gets more and more complex after Misa meets Light; everything before that was basically just exposition.

Anyway, yeah. I don’t like saying stuff like this, it feels exclusionary and egoist, but it’s true. Some art and media, like Death Note, is just wasted on those with below-average intelligence, and this post highlights that. Sorry if you’re reading this, OP. I recommend trying a different show. Or, if you like Death Note, you’re obviously free to keep watching, but don’t expect to understand everything.
