This is a seriously underrated show that shouldn't have been cancelled. It's hilarious, compelling, mysterious, action packed, and full of twists, making it a beloved staple in my family. The actors are truly exceptional, crafting quirky, lovable, and complex characters that imbue the series with undeniable charm and intrigue. They are matched perfectly by terrifyingly unusual villains, who are brilliantly acted as well. If you love sci-fi, comedies, detective mysteries, ensembles, and things like Mr. Right(2015), Santa Clarita Diet, Truth Seekers, and The Hitchhiker's Guide To The Galaxy. The cinematography and score/soundtrack are inventive and fun from the very beginning.
As for the rating, the main issue is violence, as it can get pretty gory, but if you can get past that, it's well worth it. I'd say it's appropriate for 13/14 year olds if you watch it first and tell them to look away at the right spots. There's also some cursing, but it's mostly for punctuation and humor rather than vulgarity, so in my opinion it's not a big issue.
Wish they'd bring it back, as it left off with a lot of possibilities, but at least it got a second season(which was just as good as the first, btw).
