That's true. But think,
- the slide away door with Han Solo in carbonite which leads to a huge media library
- the heated up popcorn wall thing
- the huge screen projector
-all the nice cushy seats
-The nice discontinued posters
-Another room leading to a concession stand with lots of goodies (candy, popcorn, drinks, etc...)
And all the other stuff that we don't see.
Just a regular projector itself costs $2000.00, let alone the theatre, the room, the seats, the balconies to represent the Death Star, the screen, and all the lobby stuff like the different rooms.
I'm sure it must have cost the guy over $50,000.00 :o
