Star Wars: Visions | Original Trailer | reaction to lightsabers

I'm posting this for myself as a blog so I won't lose it later on, and I will have easy access to this later.So no tags, at least for now.
Everything looked good until they started messing with lightsabers
What the hell are they doing with them?!

• 1:44 One moment they are normal lightsabers the other they behave like ropes ?
• 1:13 They are doing an Astro Boy knockoff?
• 0:58 What is it , umbrella lightsaber? Completely useless lightsaber that wouldn't block anything,The reason Jedi block blaster shots is because they use force to know where to move it to block, not just random like here
• 0:20 Ok kind of cool with pulling his lightsaber out like a katana, but generally something stupid when you look at how they work. They don't need a sheath and especially it's a stupid move to have an ignited blade that is close to your body.
  Also......, oh please don't tell me that the sheath is full size and he has the lightsaber turned on the whole time because that would just dumb.
• 0:21 Grievous needed to have implants in the brain to control all arms in a flawless way and unless she has implants in her brain (It doesn't look like that) the additional arms are useless and would be in the way if they are controlled by some AI.
