For so long we thought Dr. “Bones” McCoy was supposed to be the opposite of Spock. But being a hothead just makes you the dramatic foil. The true opposite must be driven by emotion on an intellectual level. And thus, finally, we have Spock’s long-lost half-brother show up in “Star Trek V: The Final Frontier” (1989). He’s a nutjob cult leader hellbent on hijacking a starship to the center of the bad SFX universe – where God is, of course. He creates implausible mind-melds and VR memory recalls, which makes this movie just as ridiculous as every other Star Trek flick.
