It's hard to understand how a show like this manages to be funny and emotionally satisfying, within it's short episode spans of 25-30 mins. It's even harder to understand how come this isn't that popular.
Writing, direction, acting and at times, soundtrack is all top notch. Bill Hader is terrifyingly good throughout. I don't want this review to be long, but just want to add that it's probably one of THE best shows running in right now.
