This is a show I avoided for years because any description makes it sound like just another average show; it's about a young woman in high school who solves mysteries. Everything about this show is amazing, from the dialogue to the acting to the complex and unpredictable storylines - and I can usually predict shows easily. So it went from a show I avoided to being one of my top 5 shows of all time.
It's getting a second wave of popularity in recent months because of the successful Kickstarter campaign to raise funds for a movie, which will be released next year.
