3. Star Trek: Generations (1994)
Billed as a cinematic passing of the baton from the original series crew to The Next Generation, Generations managed to fail on almost all fronts, starting with a hokey, ill considered McGuffin to enable Captains Picard and Kirk to meet. The nexus is an energy ribbon that grants anyone who enters it their heart desire.
When Picard is swept up in the Nexus to meet an oddly disengaged Kirk, a gaping hole was torn in the films logic: if the Nexus grants your heart’s desire, how is the latter half of the movie, after Picard “leaves” the nexus not just a nexus-induced fantasy?
Generations also made the mistake of providing a threat that audiences neither knew nor cared about. who cares what happens to the Veridian system?
Bereft of a climax befitting The Next Generation’s first cinematic adventure the filmmakers decided to kill off Kirk and the Enterprise-D, in equally unsatisfactory ways. It took 2 attempts to kill off Captain Kirk, after test audiences responded unfavourably to his first death, and the Enterprise-D was crashed into a planet after a torpedo was modulated to her shields frequency (what!?).
For a far better meeting of the generations check out Scotty’s journey to the 23rd century in the TNG’s episode “Relics”
