This is a way-fun series, that also leaves you proper gutted while you scratch your head. For me it seems like some really original approaches to time travel storytelling. It's like if Groundhog Day (or its idea's originator, the novel Replay) was turned into an excellent workplace dramedy.
There's some justified criticism about the main(ish) character and his ability to somehow embody keystone Kop and John Wick at the same time while making the worst string of decisions ever in fiction.
But if you can ignore all that, you'll fall in love with Archie and Shiv and the gang and the whole complicated mess!
