As for cruddy twins -- they twined a really nice neighborhood theatre in the mid-70s (the worst days of early multiplexing). As was their want, they would split it right down the middle and keep the two projectors, ports and seats in exactly the same position. This shifted the centerline of each screen's placement yet the seats, remained facing the what was the corner of the two new screens. Although the aperture plates were cut properly to correct the keystoning, any horizon lines in the image would dip in to one side at the bottom of the screen and then turn upward toward the top of the screen, creating a kind of trapizoid distortion....credits were fun to watch because there never was a parallel line anyplace on the screen. Couple with the fact that you weren't sitting facing the screen, but some mytical place further to the left or right, depending on which box you wound up in, you constantly had to overcome the sensation that the room was tilted and you were always on the verge of falling sideways.

The there was the fact that the rooms were now twice as long as they were wide. The audio sounded like it was in this big echo chamber -- nice for those who like that gym shower room sound, only trouble was, you couldn't understand not a single word of dialogue.

Fortunately just accross the street there is the Century 21, a much bigger dome that is also a former 3-strip Cinerama installtion. That dome is still intact, as are the three domes of the Century 22. (I regularly go there to see first run movies, and presentation quality is almost always excellent.)
