I fully accept the "adds nothing" screed.
I just flash back to 10 years ago. We looked at two houses on the same block, absolutely identical in floorplan and layout. Potatoes-po-tah-toes updates in both of them that we liked or didn't like. Within $300 asking price for both houses.
And the house we bought, we bought entirely because it had a "home gym" in the basement. We were excited about the "home gym."
The "home gym" turned out to be a craptastic universal machine, bolted to the wall in an unfinished basement. The first time I tried to use the "home gym" it was so rickety and decrepit that I realized it was unsafe. It was a Sears and Roebuck relic of the Pleistocene Era. Total white elephant. Getting it cut off the wall and hauled upstairs and away was an ordeal. Facepalm city.
I know that if we ever leave the house so a potential buyer can walk through, I'm setting "The Dark Knight Returns" to play on a loop in the theater. Maybe it will impress, or maybe the kids will sit on the tiered seating and veg out in the dark while their parents chew it over with their Realtor upstairs. I can see a potential buyer shrugging and saying "Ehn." I can't see anybody saying "Ew! We'd never use this!"
I also flash to all the guest families we've cycled through our theater, and the number of parents who said to their kids, "Can you imagine
having something like this in our house?"
But the world is telling me, "Shawn. It's an 'Ehn.' It's a 'Meh.' Deal with it." Okay. I accept 'Ehn.' I accept 'Meh.' I also know I'd never buy another house that did not either have a home theater or have a good space available to build another one.
