How convenient!
Most films rely on a few plot contrivances to get us from the beginning of the story to the end in just 2hrs, however this one is littered with them from start to finish:
- The Franklin and it's disillusioned Captain just happen to crash land on a nebula planet full of drone tech and the technology to prolong life (by killing others).
How convenient!
- The Federation decide to build their largest, newest diplomatic outpost (Yorktown space station) just outside the nebula, which is still uncharted space. Risky much?
How convenient!
- Krall sends Kalara to the Yorktown to bait the Enterprise into the nebula with a fake rescue story. How does he know Kirk has the artifact? How does he know the Enterprise will be at Yorktown? How does he know Starfleet will send the Enterprise to the rescue?
How convenient!
- Despite destroying the Enterprise and killing most of her crew Krall is able to safely steal the artifact from the undamaged storage room (before losing it to Kirk)
How convenient!
- Scotty just happens to be rescued by the only person on the planet with access to The Franklin wreckage
How convenient!
- Kirk and Chekov fortuitously avoid being crushed by the Enterprise saucer section (unlike Kalara)
How convenient!
- Kirk and Chekov just happen to run into the Franklin wreckage (and Scotty and Jaylah) on their way to Krall's base
How convenient!
- Scotty is able to locate and transport Spock and McCoy on-board (while the rest of the crew are captured)
How convenient!
- Krall keeps Uhura alive (but kills Syl) and tells her things which later allow her to work out he is Edison.
How convenient!
- Uhura and Sulu escape just long enough to figure out what Krall is doing (and send an S.O.S which he sabotages)
How convenient!
- Jaylah, the only alien ally they have on the planet, just happens to know the layout of Krall's base, which hasn't changed since she was a prisoner there as a child
How convenient!
- The Franklin needs to be kick-started via free fall. Luckily it crash landed on top of a steep ravine.
How convenient!
- McCoy (the ship's doctor) is able to pilot a drone ship, designed for use by robot drones, without any modifications or training
How convenient!
- Despite Krall having a significant headstart, the Enterprise is able to catch up with him and prevent his ship from reaching the centre of Yorktown by crashing into it. This is one of drone ships that destroyed the Enterprise by punching holes in its hull...
How convenient!
- The bioweapon remains passive for minutes after Krall activates it (ignoring Kirk as he floats past it) despite instantly consuming Syl earlier in the film. This delay gives Kirk just enough time to eject it into space
How convenient!
- Spock and McCoy appear just in time to rescue Kirk before he's ejected from Yorktown along with Krall and the bioweapon
How convenient!
