Season one was solid bordering on terrific at times. It really was well ahead of it's time in the "serialized drama" genre. There are a few moments where the 1980's style cheeziness is noticeable, but for the most part, it was well worth the watch.
In season two, they seemed to struggle to find a way to really keep the narrative moving. It gets a little stranger and eventually we just lost interest before finishing the last 3 or 4 episodes.
Overall, I'd give it like a 7 out of 10.
