With apologies to the Dos Equis guy -- "Star Trek" movies don't always involve time travel, but when they do, they were awesome. Original Recipe Kirk and Spock saved the whales in "Star Trek IV: The Voyage Home." Picard and company rerouted the Borg and met the Vulcans in "Star Trek: First Contact." And the new Kirk and Spock dealt with a villain who came back in time to avenge the destruction of his planet. All three movies made Trekkies squeal with glee.
