Let's just start off with a bit of background; School Days is an infamous anime based off of a Japanese visual novel, now the visual novel has about 12 different endings, the anime's ending basically shows the worst possible outcome.
This anime has some AMAZING PRODUCTION it's super solid and the people who made this anime knew what they were doing with the pacing, the music, the timing, everything was top tier. The pacing at times feels slowed down and personal which adds on to the overall tone, personal. After all, the developments of the story are dark. There's a lot of foreshadowing towards the end about the big twist with Makoto. This show is brilliant, all the characters were flawed individuals but none of them deserved the ending they received, but even so none of the actions taken by the characters were unreasonable. The grand finale was brilliant, it was dark, it was extreme but it was built up to that point perfectly. There aren't words to describe just how great the execution was of the scene was, the music, the framing, the pacing and the dialogue. Everything worked together perfectly.
We can take this anime as a cautionary tale on the consequences of cheating and how that can affect others negatively.
This anime is a unique experience, I recommend going in blind when watching this anime. It's definitely more surprising without the spoilers I was unaware of that and unfortunately made the wrong choice and got spoiled but even so I was still shocked by the events which transpired towards the later half of the series.
Flaws: The middle part of the anime felt long and slow, for me it was a little boring, for others it was regular pace. Some even complain that the last few episodes felt rushed however i myself I enjoyed the pacing at the beginning and towards the last 3 episodes.
Overall I would give this anime a 8/10. This anime could of went in many different directions but it was clear from the start that the anime wanted to use this ending and it was well made, plus I enjoyed it. Honestly I understand the arguments for why this anime was a dumpster fire but I have to give it some props because I enjoyed watching.
