I agree, these kinds of setups look ok for a theme park or something, but I really wouldn't care for them at home.
Some ethnically thematic architecture is one thing...
You would lose a lot of money on something like this if you had to sell a house as well. Some potential buyers may simply be turned off by the design as well.
If I were to do anything like this, I would make it a lot more subtle than these examples. Perhaps a little design work on the ceilings or borders along with some columns. Do a sand/eggshell colored theme similar to my own theater perhaps. In other words, pay homage to what you love but don't go crazy... unless you are designing for Disney World.
in that last set of pictures, the screen is pretty damn small after all that effort ... prioritize object oriented 3d audio first... and then all this other stuff.
