I am quite surprised that this sits in the bottom three, it's definitely not one of the better episodes, but it has a certain charm.
Right from the off you can see that it had a Psycho influence, even the word Motel makes it feel like the aim was to appeal more so to an American audience, as was the use of Robyn Millan as the central character. The trouble is, her delivery is rather odd, I can't make out if she's playing a slightly neurotic character, or if her delivery is just a bit odd, however I really like her in it, I watch her as she's so quirky. Derek Francis is also good, the episode does have comic undertones, considering the dark story, it's delivered in a fairly light way.
You're questioning whether everyone that visits the Motel is part of some twisted murder game, or if there's something else going on. Some nice, tense scenes.
It's better then the score would suggest. 8/10
