- The unknown ensign dies (if that's a spoiler than you really need to read up on your sci-fi) - "I'm a doctor, not a physicist!" - "I'm giving her all she's got" - The clubs still included 1960s garb, even though it was the 23rd century - The time travel and science still made no sense and obviously were there solely as a cheap plot device, but I loved the movie so much that I didn't care!
