The most complex and intelligent of the Trek films, originally intended as a metaphor for the end of the cold war, one could also read it is a prediction of an eventual detente between the West and Islam (if one has the necessary Trek optimism.) Good comedy, great action sequences, Sulu promoted to Captain, Worf’s grandfather, Kim Catrall as an evil Vulcan, Christopher Plummer with a nailed-in eyepatch, globules of purple Klingon blood floating in zero G — you just can’t go wrong. I worked at the local Loews when this came out and I think I watched it fifteen times.
