Haven't played the game but I've seen the show and it's pretty "meh." Now that I think about it though, Defiance bears a lot of very similar themes from another past-SyFy show called Eureka:
- Man stumbles upon a unique town full of eccentrics. - Man has a rebellious daughter. - Man ends up being the sheriff of this town. - Man has a close flirty relationship with the town's head female. - Man usually ends up solving or fixing the town's problems for the episode with his common-sense which no one else in the town has.
Eureka was fun in bursts if you wanted to turn off your brain for half an hour, but it quickly got repetitive and a bit boring. Although surprisingly, the show did run for a lot of seasons so Defiance could only hope to be as lucky.
