I'll just quote James Lileks here:

Ask yourself: if you and your friends decided to shoot an entire episode of TOS Star Trek, and you wrote a script set on the recommissioned Exeter, and you rented a warehouse, built a replica of a Constitution-class starship, designed all the sets and lighting to look like 1967 TV, and spent SEVEN YEARS on the project, meticulously recreating the look and sound of a TOS episode, what would the result look like? It might go something like this. Ladies and Gentlemen, I give you Starship Exeter.
