This is a really great show now airing it's second season on Sci-Fi. The premise is that a town was erected in the United States where the worlds greatest minds could unite and create together without having to worry about regular folks mucking things up. So the town is jam packed full of people with handfuls of PhDs, constantly inventing new things, and often creating new problems.
Enter Jack Carter, a US Marshall who stumbles upon the town when picking up his semi-estranged daughter from her latest run-in with the law. In his exploration of the strange town, events transpire which lead him to become the new Sherriff. In his new position he is often called on to solve the various muck-ups the many colourful scientists create, despite being probably the least educated person in the town.
This show is a blast. There are dozens of wacky scientists, great plots, and great application of Carter's everyman wit. Despite being a sci-fi show with relatively detailed science fiction plots, the show is more of a comedy, and has the characters interacting very well. This was probably my favorite show of last summer and I can't wait for new episodes to air.
