Can someone explain the bee significance? (obvious spoiler)

- why the bad guy was BLIND when he makes whole humans including eyes

Why is Stephen Hawking a scientist when he so clearly has a disability? Nikola Tesla was known to be very reclusive. Did that mean he wasn't allowed to do his work because he had a disability? Toward the end of his life he refused to eat anything but fruit. Great scientists often times have the greatest idiosyncrasies.

- what happened with the huge room of children? oh nothing.

That scene was there because of the memories "K" had that were implanted by Stelline. That place was were he "hid" the horse carving. The presence of the scene was not meant to "be" something, rather a key to that memory "K" had. He found the carving of the horse that he believed meant he was the child of Rachel. That room was showing how the children were being used as slave labor. Clear enough I think.

- why did wallace birth that replicant just to gut while dialogging?

He "birthed" it with the purpose to see if she could give birth. He was having an issue with not being able to mass produce his replicants. If they could reproduce on their own, then his job was done. Being blind he had a "second sight" that meant he was able to sense in her that she was defective. He killed her because she was defective.

- why was everything so huge, world breaking and important, except that it wasn't and no one really cared?

The world the original took place in was huge. I suppose you don't remember the Tyrell pyramid? Please don't try to make sense out of something if you don't want to do the mental work.

When "K" got to Las Vegas to find Deckard, he approached the building where Deckard was and before he got to the steps he found the apiary. He slid his hand inside bringing it out with a lot of bees attached to it.

folks,

all the answers so far boarder on speculation...

The bee-protein-Dekard theory seems weak (no offense intended).

Today, bees are a crucial part of the Eco-system mainly due to the part they play in cross-pollination. Pollination=vegetation, but the bees in the scene were in what appeared to be a very arid environment, almost Saharan. Doesn't add-up.

Also, Although replikants are "superhuman" I'm not sure they'd be designed to be completely immune to pain. Could it be the bees simply lacked the ability to sting because they too are engineered??? (anyone catch the Black Mirror episode about drone bees)

Again, I am speculating as well, but it's only because the responses so far aren't convincing enough

Voight-Kampff test (called The Empathy test in the original Bladeruuner 1982)????

Please elaborate

nonsense. There's a reason for it. That's why this film is so good; it challenges you to think.

Good points, but your ‘How are those bees supposed to be able to survive?’ flaws your theory somewhat. That place was like no-man's land, like a once before inhabited Outback. I like what you said about the bee's giving K a clue that someone put them there and is using them as some sort of food source. I also like the idea that he (K) may have never seen real bees before and therefore was simply mesmerized for a moment. Interesting.

I'm afraid you mixed-up your movie universes with the "neat wooden toy in Witness" comment. Deckard wasn't in Witness; that was Harrison Ford playing a different character named John Book...LOL!!!

The poster who called that scene distracting sums up my reaction to it, too. Without a plausible and valid explanation for why it's there, I'm standing by my above statement it's only there to look "cool and weird." And at 166 minutes, that scene could have easily been omitted without detracting from the story.

I still liked the film, but it wasn't perfect.
