To me this looked like Season 1 was such a success that everyone wanted to rush Season 2 to production to strike while the iron was hot. The 2nd season watched like the writer had an outline with no real substance. They went into production and winged it. Looks like they had a different director for almost every episode which you could see with the dropped story elements.
I bet they were writing most of the dialog right up to the moment of filming.
