Well, last night I made a terrible mistake, I went to see 'The Last Jedi'. It's probably the worst movie of all nine and to show what I mean I'll concentrate on the mistakes and leave the acting alone for now.
1) Bombers in Space
At the approximate height that the bombers were operating there would be little or no gravity so how are the bombs supposed to fall? In any event one bomber does manage to release it's load and the bombs fall straight down, this is also wrong as the forward movement of the ship would be added to the trajectory and the bombs would fall in a curve.
2) Spaceships Stopping Dead Due to Lack of Fuel
According to Newton's Laws of Motion, a moving body in space will continue to move in the same direction until subjected to an outside force. Spacecraft use their engines only to accelerate and decelerate and if that engine dies from lack of fuel then the vessel will coast in a straight line along its present course whilst maintaining its speed.
3) Spaceships Traveling at Light Speed As A Weapon
Jumping to light speed then ramming another ship, cool idea, why didn't the rebel alliance use this as a weapon before now? Two old clunkers sent into action and both Death Stars would be gone, a few more and every Star Destroyer would be wrecked.
4) A Rebel Base With a Back Door
So, you build a rebel base and equip it with the biggest strongest door the galaxy has ever seen, you then ignore the cave system behind you that has a back door covered by a small layer of boulders. No problem chaps!
5) Leia and the Bridge Explosion
This COULD have been used by Disney as a vehicle to write Carrie Fisher out of the script. If there is a rapid atmosphere release on a spaceship and you're sucked out then you continue to move away as your blood boils and you freeze to death (and this happens within seconds). But no, instead the Princess flies through the void like superwoman and, surprise surprise, she's still alive.
6) The Scar
So, they can travel faster than light, destroy planets and build androids that can speak and translate multiple languages. They can't however make a simple scar on the face vanish.
7) The Dudes in Red
After Snoke is killed why do the dudes in red attack? Their master is dead and Kylo Ren is their new boss so why are they attacking him and Rey?
Finn and the Cannon
Finn rides one of those beat-up salt skimmers right up the radiation beam of a big honking space gun. Why isn't he dead?
9) Master Luke's Arm
When at the end Jedi Master Luke Skywalker ascends, or whatever dead Jedi do, why does he take his artificial arm with him?
10) The Scene in the Mirror Cave
The scene where Rey falls through the hole in the ground and encounters multiple images of herself, what was that about?
Maybe this is because of the dumbing down of America, maybe Disney have no actual scientists on the payroll, I don't know, but if this is what the new Star Wars is going to be like I'm not watching anymore.
