I thought it was kinda... okay. Not great but not bad, either. I will continue to see it a few more to see if it grows on me. Dialog was horrible at the beginning, and the personalities involved just didn't do much.
I thought it reminded me a lot of Torchwood, when the big reveal came (welcome to the sanctuary) a pixie instead of a pterodactyl flies overhead. There is a long conversation on the roof between Gwen and Jack.. I mean Magnus and the doc. And Magnus, like Jack, is a lot older than he/she looks. They replaced the aliens and technology with the supernatural.
I did think Amanda Tapping looked hot, but I like brunettes and women in dresses. Didn't think much of her accent, it seemed off, even if she is from the UK. I watch lots of British shows (Top Gear, Torchwood, Doc Who, Trinny & Susannah) but she just sounded odd.
