Unless you're unwilling to compromise on screen size or have some other extreme edge-case deal breaking scenario like needing the center-channel behind the screen, a projection home theater doesn't make sense. It's a waste of money and it's worse in many ways.
A lot of hobbies are like this. The expensive stuff there for some stupid reason people won't compromise on.

They are more focused on having it & showing it than how well it actually functions for them.
