Series
I thought S1 was pretty good. Interesting storyline that kept me wanting to watch to get answers.
S2 was decent but it seemed like the writers were taking plots I a lot of directions, and the interest started waning.
S3 went off the rails in my opinion. It kind of seems like the writers may have needed a couple additional seasons to adequately tie things together and keep it interesting. Instead, it was mashed together into a cluster.
I suppose season to season concepts can get pretty tricky to keep things flowing, but this one went sideways.
