It is an amazing and one of the most underrated series. Beauty of the series is its story and how they hold onto it till the very last episode, it is different bit of unseen but perfectly executed. You can not expect regular laughter like you do while watching FRIENDS and Big Bang but it will definitely makes you smile regularly.
The only negative thing that I feel about the series is they ended it bit too early, could have continued for another couple of seasons.
