Steve Martin and Martin Short are great in this. Selena Gomez can't really act and has to always be carried in pretty much every scene. She can do things(like walk around, be sneaky or do some action scenes) but when it comes to actually acting, she can't really do facial expressions. You can really see that in the scenes with oscar and her mom, where it feels like a crappy cw show. I don't know how she got past audition.

The writing, directing and sound design are all great but man Selena Gomez really adds nothing to the show, thankfully they don't have too many scenes focusing on her face while she is acting so we are spared a bit.
