SciFi movies and pathetic misconceptions of tech failing for the story line.

Among the many things that annoyed me with Interstellar is the way that they have a super shuttle which can pull itself out of the gravity well of a planet near a black hole with only its internal fuel reserves, and yet the same vehicle needed several stages to get off from Earth at the start of the mission.
Another annoying thing I've found is something that occurs often in superhero films. If we accept that the superhero has extreme strength and is virtually immune to injury then why:
a) Is a superhero able to restrain a helicopter from taking off without clutching an immovable ground fixing at the time, however much strength he has he cannot prevent take-off when the helicopter's liting force is greater than his body weight.
b) Does a superhero flung out from a fight plunge throuhg all manner of debris and keeping moving for hundreds of metres before halting, sure he might have impenetrable skin and somehow survive the extreme decelarations involved in the series of collisions, but conservation of momentum means he'd come to a stop, however fast he was flung, within the course of the first few big objects he hits purely due to him having only a roughly typical human's mass.

maybe the engines only operate in a vacuum, like advanced ion thruster technology, not suitable for lift off in the atmosphere because they would destroy themselves with plasma
alot of technologies would have a problem in the atmosphere at high power level, like blooming

Niven once pointed out that a huge dust storm on Mars is about as dangerous as an enraged caterpillar.
The radiation hazard on the other had is considerable unless everything is buried.

Firefly is the *only* show or movie that I have ever seen showing how a ship properly descends into a lower orbit for entry into the atmosphere. I almost jumped up to cheer.

Forward takes you out, out takes you back, back takes you in, in takes you forward.

I really want to see inertial dampers made in my life time. Hopefully connected to a ceramic resistor bank. And the bootleg space ships will use a salt water load in a tupperware when the manager does not want to buy a new load. How many watts do I need to dissipate to prevent my coffee from floating away?
Is that a shady practice done on large ships? Like discharging a battery bank into the hull ?

I'm about to watch 'Deus The Dark Sphere (2022)', will it be interesting, or a dud?
