On totally unrelated news, Popcorn Time 4.0 was recently released and using it is decriminalized in many European countries (but not in others, so stay safe):
Also, always using sequential downloading isn't very good for the swarm; it means that disproportionately fewer seeders are available for the later chunks of a torrent.
I'd recommend downloading the first episode or two sequentially, but downloading the rest of the torrent normally (or perhaps just first/last parts first).
