I didn't like S1 at all in first run, S2 first half, I found myself starting to appreciate some episodes, and by S2 second half, I was enjoying it, and thought it had been a good a show, and was a shame wasn't going to continue.
A lot of people feel that way too.
It took the writers that long to find their footing.
I'm hoping when I rewatch, I'll be able to enjoy it from the beginning.
Some have said that the first season plays much better if you can watch the episodes back to back.
