Rubbish. Exceedingly and unnecessarily slow, heavily reliant on people in an almost-abandoned town making questionable-borderline-on-stupid decision after decision to further the plot. This could have been wrapped up in 3-4 episodes had people not reacted unrealistically and done the reasonable thing.
***SPOILER ALERT***
If you have doppelgängers walking around your town, I’m sure the reasonable thing is to NOT talk to the police and instead welcome them into your home.
