Big Little Lies - I really liked this show based on the novel of the same title. It had a murder mystery on hand - who died, and who did the crime - and it focused on the lives of these women and how the whole event ended the way it did. The adaptation did take some creative liberties, but it is still a solid show with a fantastic cast. I'm not really sure about the second season, but when it rolls around, I will still watch it.
Sherlock - I wanted to go with Elementary for this one, because I spent the last year binging on 5 seasons, but in terms of being closer to its source, Sherlock seems the way to go. It is about the adventures of Sherlock Holmes and John Watson, and how they go and solve crimes. I still haven't seen the last episode of this show, and heard how bad it was that I wanted my memories of this show to be just the positive (and so I won't have a problem binge-watching this in the future).
A Series of Unfortunate Events - The main theme of the show was stuck in my head for a couple of weeks! This is a story of three orphans and their misadventures in life, particularly their encounters with Count Olaf. With only thirteen books to adapt, this show has a small life span, but the adaptation was done very well.
