'Nightflyers' turns George R.R. Martin novella into Syfy pretender

Having created the blockbuster "Game of Thrones," George R.R. Martin's works are suddenly in high demand. But "Nightflyers" -- a series based on a 1980s Martin novella -- proves a tediously generic haunted-house-in-space odyssey, one that Syfy is either (charitably) experimenting with or (more likely) rapidly exhausting by making all 10 episodes available simultaneously with its linear-TV debut.
