So far, each episode seems to be formatted like this:
Some character development, a mystery involving a ghost/supernatural forces, foreshadowing of a bigger plot. (And this pattern has stayed consistent on the episodes I've seen so far...)
Obviously, with a pattern like this one or all of the three has to be sacrificed and we end up with a mystery per episode that is neither challenging to us nor expanded well on. Just a plain "oh here's an issue, here's -briefly- what the characters did, and here's the solution."
It's not a bad formula but for people who are expecting/wanting a more dramatic or drawn out mystery, it might not quench your thirst.
The nice thing this series does (so far) is that despite the rather short "character development" segments it is done rather cleverly and leaves you a little curious about more and whether they'll have a bigger role later. Same can be said about the segments that seem to "foreshadow something bigger" except they are even shorter and may prove more of a tease than anything.
Overall, so far it's an average standard show, it doesn't have a crazy "cliffhanger ending" pacing nor is it so slow you wished the episodes would air faster.
((Edit/Note: in the later part of the series the pattern has changed so that character/background development has become a bigger part of the episodes-- however this results in the "mystery per episode" parts needing to be stretched beyond one episode, which can be both a good or bad thing depending on whether you mind cliffhangers or not))
Neither epic nor horrible --a series that one can check out if you have the spare time to spare. But it's not a great loss if you don't check it out.
