This was mostly really average until the mystery was explained, then it was kind of poor and waiting for the reveal to be told but episodes 11 and 12, especially 11, was absolutely horrendous. I don't remember watching an episode as painful as that one.
There's really nothing good about the show besides maybe the mood set up by the eerie score earlier on. The dialogue is kind of bad, characters are really bad and barely one dimensional, the plot is ridiculous, I don't remember a more contrived anime or even show I've seen. The amount of times we are about to get crucial information and someone or something conveniently interrupts was ridiculous.
Another is literally just another anime that does nothing to stand out and has bottom of the barrel writing. If you want a good laugh I suppose I'd recommend you watch episode 11, words can't do it justice in terms of how laughably bad it is.
