Repair bots on the hull was like
The Phantom Menace, but instead of R2 units the robots looked like Eva from
Wall-E.
Inception gravity defying rotating corridor fight.
All the fighters and shuttles forming a protective "shield" around Burnham was like
Ender's Game when the drones protected the doomsday weapon ship.
2001 wormhole lightshow effect. Just needed a starchild Michael.
TMP wormhole effect on the crew, and with the grid pattern in space as Michael transitioned through the wormhole.
The Enterprise fighters looked sort of like the Mars Defense Perimeter drones from
Best of Both Worlds.
The Leland-1000 getting the nanites pulled from him by magnetism was like
T3 and
Terminator: Genysis.
The top-down view of the perimeter defense systems taking out the Section 31 drones in a massive ring of explosions looked a lot like nu
Battlestar Galactica, just with phasers instead of cannons.
Burnham totally did the superhero jump off the debris to lead Discovery through the wormhole. It was very
Iron Man with the suit.
Before we get any premature
Abdinication, I don't consider any of this ripped off or even necessarily intentional (though I have to believe they were making the
Inception "BWOMMMM!!!" sound in their heads while filming that corridor fight), but there's nothing wrong if it is either. This is just some of the stuff that came to mind as I was watching the episode.
