And I think maybe you’re joking about 2 projectors and a rig not being that pricey? Obviously everyone will have a different income level so “expensive” is relative, but I would guess that for most people, the projector is the single most expensive piece of equipment in their home theater. Doubling that price, plus the polarization rig, just to use passive vs active lenses is a bit extreme for a lot of people. If you’ve got the disposable income to do it, by all means, more power to you and I am jealous!

On projectors, I have noticed that they do not really hold their value on the used market, so buying 2 decent projectors for a few hundred bucks total is doable.

For example, I needed a Full HD 3D projector that I could travel with, and after a few weeks casually looking on eBay I landed one for under $200. In the $300 to $400 range you could likely buy it now, since factory refurbs seem to be from $350 to $500, which puts a relatively solid price ceiling onto used projectors

With some patience, 2 Full HD 3D projectors and a polarized screen could be done for around $1,000, more if you buy a rig to align them. That's a somewhat serious sum, though it is about twice what Sony sold that PS 3D TV for, which Linus considered to be terrible, and it is 1/16th of what he said his cream of the crop 3D TV retailed for.

Passive not only is cheap it also doesn't have the downsides of active glasses, you may be proud of your TV and glasses set, but most people aren't prone to have complicated gizmos and to have hassle with them.

DLP-Link active glasses are incredibly simple to use. Just turn them on and they work, a rare example of a plug-n-play technology working. They sync themselves, the most work you'll have to do is to click a button on the glasses to invert the sync, and that's not always required.

Natural light, and even artificial light, aren't dealbreakers with 3D on a projector. They wash the image out, of course, but the tech can still work with some of them present. Although IMHO a movie should be watched in an environment with minimum light.

My active 3D glasses have gone through many episodes and films on a single charge. I did have a pair run out of power the other week during a film, but swapping in a spare pair only took a few seconds.

At $12 to $20+ a piece, active glasses are significantly more expensive than passive glasses. For a movie theater that has thousands of patrons that matters, but for a home audience I'm not sure it does. Anyone who can afford passive 3D projection can afford dozens of active 3D glasses. It seems to me that 3DTV owners don't need to buy that many glasses as only a few people can watch a 3DTV at the same time.

As i could watch on that video, Playstation 3D Display had also 720p on active 3D. Maybe that's why people stoped to like 3D. Playstation as a great brand selling bad 3D displays hurts whoever who bought it.

With active 3D, in a darkened/dark room, I have not had an issue with the glasses reflecting the 3D movies.
