Trekkies is hilarious, fascinating, and, at times, almost scary.

This valentine to Trekkiedom (produced by, who else, Paramount) doesn't go in very deep--probably doesn't intend to--but it's also not quite the promotional piece the studio may have envisioned.

A laid-back excursion through the "Star Trek" phenomenon that boldly goes where millions and millions of fans have gone--in and out of costume.

Trekkies is a hilarious work, mining the psychology of the average and not-so-average Trek fan, and coming up with the answers to all your burning questions about the show and its devoted following.

Trekkies talk at length about how the world would be a saner and more peaceful place if the "Star Trek" philosophy ruled our lives. No doubt it would be a lot more entertaining, too, especially during root canals.

It doesn't analyze or explain it; it just presents it. The result is funny and disturbing at the same time.

By the end of Trekkies,you almost feel the best way to bring peace to the Middle East would be to hold a Star Trek convention there.

Trekkies doesn't quite take us to the final frontier, however, it is the best documentary on the subject and a good laugh.

There's a great deal of love in Trekkies, Roger Nygard's warm and good-naturedly funny documentary about the world of Star Trek fandom.

It is probably hopeless in the presence of Trekkies to do anything but sit back -- amused, bemused and astonished -- and watch the devotions of fans of the various incarnations of "Star Trek."

It's always nice to see real people, however eccentric, enjoying their lives; if Star Trek has anything to do with that, more power to them.

A largely affectionate look at the weird and the wonderful subculture that's ensued and endured since the sci-fi series first beamed up in 1966.

Roger Nygards’ sweet, gently funny documentary about the wild and woolly fans of all things Star Trek doesn’t really reveal much about the original landmark series and its various spinoffs, nor does it ever really get to the heart of the shows’ enduring appeal.

Most of the extreme Trek fans it features are obsessed in a big way, and if they were your children you'd probably be thinking therapy.
