I really enjoyed this first season and it's characters. It takes a while for it to find its footing but when it does it sticks the landing. The performances from the actors are great and I like their relationships, I just wish that they could've had some scenes all together at some point besides the first and last episodes. 
One of my main problems is the treatment of Vania. She is treated terribly by everyone around her until she finally breaks. I don't like that Allison is just correct in the end and that Leonard was a bad guy. I hope season 2 gives her some nicer endings.
Klaus, Ben and Allison are the standouts as being really funny and a delight when they come on screen.
Diego and Luther on the other hand while sometimes being entertaining just come off as annoying because of their bickering. 
All in all it was entertaining.
