Be on your guard. There are older and fouler things than Orcs in the deep places of the world.
I'm on the fence over it but willing to give it a few more tries watching. ...The plots from the first two episodes seem to be more cheesy Starsky & Hutch than Lost or Fringe. Neat concept but very pedestrian writing.
If you're a Fringe man, you'll probably remember that season one was fairly pedestrian as well. It didn't start getting "very good" until about a quarter of the way through the second season.
