Locke & Key (3 Seasons)

A grieving family moves into an old house where they begin to discover magical keys that do all sorts of cool and dangerous things, often needing them to solve problems that they created in the first place! While I laugh at where some of the keys were "hidden", the story starts off quite well and most of the characters are likeable enough.  

Alas it slowly degrades as things happen that just aren't explained or worse, characters become stupider - because the writer's couldn't handle what I call "the Flash syndrome". They get all these powers that are super handy and... forget to use them? Also, in Season 3 they are still blindly testing new keys with no contingencies which is really moronic.

Still an entertaining series though, and one with an ok ending despite the convoluted path it took to get there. If you like the "dark fairy tale" vibe (but not too dark because the creators still tried to be kid friendly) then definitely check this one out.
