Fantastic season 1. Really witty and exciting, keeps you on your toes and leaves you wanting more than the 6 episodes.

Mediocre season 2 with a horrendous ending that ruins the entire show and makes me lose all interest in season 3.

The two main characters are amazing and steal every scene they're in. The supporting character are fun and interesting in season 1 and completely boring and without any sort of substance in season 2.

A bit of a shame Jon Hamm's character isn't given more to work with, but that could have been forgiven were it not for the horrible ending of season 2. As it stands, wasted potential.
