SyFy took a big shot with the costly George R.R. Martin drama, “Nightflyers,” which the network co-produced with Netflix. Unfortunately, its investment didn’t pan out as envisioned. The ambitious show was canceled in February after only one season, despite initial plans for a multi-season story. According to The Hollywood Reporter, low ratings are primarily to blame, with the series failing to break out in an already crowded space of original TV content.
