Personally, I couldn't really care if the movie was well written, well directed, well this, well that from a film making perspective. Heck, probably all of the OT would be the same. SW is probably the best universe for spoofing and making satires of. There's probably a reason for that.
All that matters to me, and likely anyone else, is if I liked it or not. Personally, you could probably pick apart much of the music of today's generation and expound on how it's actually poorly crafted from a "music composing" standpoint. Bottom line, it sells because there are people who like it; they don't care if the chorus if the song is correctly structured, if there's the correct amount of verses in the song, etc.
You misunderstood me. The concept of a sword that is just a laser; a weightless beam of light that has solid properties, also makes no sense.
There are tons of well made films that I don't particularly care for. It's a thing called taste. Everyone has it. Some more than others.
As for the science behind lightsabers... yeah, you can't really explain it. I like to imagine that the kyber crystals warp a high intensity light into some kind of permeable thermonuclear fission. All the Jedi walk around with nuclear warheads strapped to their hips.
It would be so cool if he had 2 LED arms, so both lightsabers could light up 
I've been behind in this thread, but have these been posted yet? From Rebelscum:
Great look at the headsculpt and Dooku's lightsaber. I'm very impressed by that likeness. Spot on.
