Highly illogical: Why every incarnation of 'Star Trek' needs a Spock

You say you're fixing to make a new "Star Trek" show? Here's what you'll need to get started -- the five essential building blocks of "Trek": If you don't know what nacelles are, rethink your involvement in the project. They're a great big dollop of high-fantasy magic in the middle of your serious science-fiction, but look, if you're making "Star Trek," "scientific accuracy" is a concept with which you should expect to enjoy only a passing acquaintance. And anyway teleporters are an efficient, ruthlessly expedient way around a host of narrative/logistical roadblocks. Just accept them, you'll be thankful later.
