I'm so utterly confused by all the praise. This is Twin Peaks with the editing of Moulin Rouge all packed together in a mystery without mystery. There's barely any investigation, just go to a place, get exposition and there's the answer to the mystery.
I keep seeing people calling this protagonist smart and capable when it takes him THREE EPISODES to notice that one of his eyes is a different color. None of his friends notice, his adoptive family just accepts it and you think it's just heterochromia until he suddenly goes "Wait did I always have a blue eye?" The only people that notice something as obvious as this are him and the main villain and if you think that's the worst of the inconsistencies you are in for a ride.
The script is full of inconsistencies. You have what feels like Dale Cooper as big titty anime girl drained of personality for some reason talking about the strange local delicacies and culture to her recorder. A few episodes later you find out she and her other personality grew up there. Characters have no consistency. They will be as dumb or as smart as the plot needs them to be. The main villains literally win at one point, murder everyone but the mc cause of his power and an ally who can conveniently be there to restart the loop.
In the most recent episode, the main villains who have a tracking device on the mc and just need to kill him quick to win for some reason take an hour to just go at him in the dumbest way possible. People keep talking up the mind game aspect when the villains just do a charge with all their followers at him in an open field, then go into a trap that they know is a trap cause they just assume no one can hurt them. And then they get hit with all of it. The protagonists have basically won here, but then the main god antagonist who has been shown multiple times to just be awful to the main cast gives a quick 'don't' and that's enough to make the mc's stop killing her long enough to escape and drag out the episode count even longer as the mc gets shot by the villains. And somehow the mc despite being guarded by his manic pixie childhood friend girl to her surprise reveals he made a bulletproof vest in like ten minutes off screen somehow. Not borrowed from the useless cop side character, he made it off of google with no one noticing on his side so we have a dramatic beat.
And oh god the fan service. I like fan service. But it needs to fit. Every episode it tries to keep a serious tone while having stupid pointless fan service that keeps getting clipped back to at least once almost every episode. It reuses the same face slam into titties and little sister panty shot throughout during scenes that are trying to be serious. Hey is it true you tried to kill me? Here's a panty shot of when I fell into the water while we discuss this.
Annoyingly I love doppelgänger horror. There's so much fun you can do with it from Body Snatchers to Lake Mungo. But this does nothing. It constantly overcomplicates simple concepts to sound smart. Oh hey the mc needs to live x amount of time for the universe to make a new save point or else he'll probably die forever. Sounds simple right? Get ready for a four minute scene making this sound like a quantum physics problem. Also I can't state how many times it goes "We are perfect copies of a person." while the clone acts like a dead stupid husk of a person.
Alright I went on long enough. I don't want to be mean to the fans of this, I just do not understand at all what people are seeing in it besides it looking nice and some of the girls being pretty. All the mysteries get dumped out early on, the tension is constantly undercut with bad writing and it has the mental effort of two people sitting at a chess board and trying to beat the other to death with the board. Fuck this show 1/10.
