I just binged the entire season the past two days and I really enjoyed it. Wood, Newton and Hopkins are just great, which was to be expected. On the whole the cast has been good, even McPoyle.
I am glad I went in knowing nothing about the movie. IMO, this show has a similar feel to Carnivale, which I also really enjoyed.
My theory is that Wood might actually be Arnold, and that Bernard is the original Wood. I know the prevailing theory is that Bernard is Arnold, but I think that if Arnold is talking to some of the hosts, it would have to be Wood doing it (unless it was some built in memory). Plus, Wood seems like he has the obsession that was attributed to Arnold. He could have been so obsessed that he killed Wood, stole his identity and destroyed all memory of himself so that he could go forward with his mission to create truly conscious hosts.
