If someone asked me what the defenition of masterpiece is, I'd show him/her this specific anime.
The main focus on this anime is its fascinating story, which, revolves around an average 29 year old guy, wanted to be a manga artist, but he sucks at story telling (the irony), so he gave up and started working at a pizza place.This guy has a strange power that he calls "Revival", which, consists of him reviving a period of time whenever a bad thing is about to happen, hence the name Revival. So good so far, until a Revival changes his whole life (not an expression, you'll actually understand this sentence once you see it).
The first episode kinda shows what I said above and I highly doubted something good would come out of it, and oh boy was I wrong, this is easily the best anime that I saw as far as story goes. There are some exceptional ones tied up in 2nd place but this one for sure takes the lead. To sum it all, if you care the most for its story rather than animation, which is actually not bad, but not great either, this is my #1 recomendation to you, I'm sure you won't regret a single second you spend on this.
