I love the look of John's room; those seats look great, and I think they were a spectacular value.
I'm kind of with Greg, though. What I like about watching movies at home is actually sitting on the COUCH next to my wife. But I do not have a dedicated HT room, so that certainly changes the equation for lots of people.
I guess it just depends upon how often you entertain in your HT and how many guests you have. Again, not only space but also lifestyle come into play. Even if I had the money and the square footage, I'd likely never have the time to entertain that many people often enough to justify such elaborate specialized seating.
It's kind of like "the only thing better than HAVING a Boat, is having a FRIEND with a Boat"
