Star Trek: Enterprise turning the Vulcans into villains was a controversial move, but it worked because of T'Pol (Jolene Blalock) in Enterprise season 1, episode 7, "The Andorian Incident." Enterprise is a prequel to the rest of Star Trek, but it's set 88 years after humans and Vulcans formally met each other in Star Trek: First Contact. Enterprise broke the belief that the relationship between Earth and Vulcan was smooth sailing after Dr. Zephram Cochrane's (James Cromwell) historic First Contact in 2063.
