Up through episode four now, and it is compelling.
One of the downsides that I can see from releasing all of the episodes at once is that it stunts online discussion. I'm reluctant to spoil anything in this thread, just as I'm glad others are reluctant to spoil it for me. But I'm a frequent poster over at AVS, and I enjoy discussing popular shows each week as new episodes air, speculating on the direction of the show and what happened in the previous episode. I feel a little robbed of that here, because I'm not going to seek out discussion until I've seen the entire season.
