Episode 5
That really wasn't all that bad. It was a pretty pulpy episode, but nothing that wasn't really already telegraphed in previous episodes. The mystery angle of the show was always going to be like this anyway. Not that it's a good thing, but it is what it is!
Worst parts of the episode would be the scene Kayo's mother comes out of the house with the garbage bag with that EVIL GRIN on her face, the camera focusing on THE LAST SUPPER on the wall when Satoru was at the manager's place, and the hilarious pseudo-ominous camerawork in the scene where the manager talks to the politician. Those are the over the top bad directing traits which drag the episode down, but we've had tons of that in previous episodes too - red eyes, evil grins, ominous meeting scenes, same shit different era.
Story-wise, the most nonsensical thing is why Satoru is even on the run. There is no evidence against him, there is only an "eyewitness" account which is a misunderstanding. He could easily have turned himself in at the start of the episode and would save himself a ton of trouble. I mean, it's not like he has some grand plan that requires him being a free man. If his plan is to trigger Revival again, there's no reason why that can't happen if he's in a holding cell waiting for shit to be sorted out!
I think it's because he ran away from the scene, with the blood on his hands in a panic which is understandable and then he got flung back in time before he really could calm himself down.
By the time he's back he knows he failed in his mission to save her, and even if he would be cleared in like 5 minutes (which I think from his pov is a gamble, probably fueled by fear) the chance that he would get detained would limit the sources of info for figuring out who the killer for real is.
I do hope it comes up in later episodes why he didn't turn himself in earlier so we get his view at least. Even if it's stupid.
