Didn't enjoy it as much as the others, felt rushed and with enough concepts for at least 2 or 3 episodes, rather than one.
The whole Scully subplot was weirdly disjointed and her family dramas just weren't that interesting.
The main story was so-so, with some excellent touches - the flashlights and 'X' formed by the beams
, some uber-gory violence and a suitably monstrous presence tempered with comedy (the incongruous slaughter soundtracked by Petula Clark
).
Overall, meh, but with enough moments to not lose my interest entirely.
My housemate, on the other hand, fell asleep 2/3 of the way through.
