Spock’s half brother hijacks the Enterprise for an obsessive search for God.

While the previous two films were directed by Leonard Nimoy, this time around, William Shatner took up directing duties to mixed results. The duo returned to their respective roles as Spock and Kirk for the 1989 film, which features Spock’s half-brother Sybok, who ropes the Enterprise crew in on his search for God (oh yes). While fans were disappointed in Star Trek V for the most part, mainly with its lofty quest and poor digital effects, but there’s still some great parts to the film, like the flashbacks to Spock’s painful childhood moments.
