Wellington Paranormal is fantastic. I'm halfway into season 2 so far. It started
out good, but it's just gotten better and better. I mean, it wasn't unexpected that it would be great, seeing as it's created by Jemaine Clement and Taiki Waititi. If you are a fan of their other stuff (Flight of the Conchords and What We Do in the Shadows), then Wellington Paranormal will be right up your alley as well.
Here's a trailer (and no, even though it airs in the US on the CW, it's not a CW show).
