This show was my first experience with Bryan Fuller and I fell in love. This is the least morbid of his shows, so it is a good one to start with. Just know going in that Bryan does not take himself very seriously, so it may be a bit quirkier than you are used to.
This show is exciting, emotional, and surprising. I love the characters so much, so I find myself invested in every situation. I'm not sure how realistic many of the situations are, but I appreciate this show for what it is.
