Well the multiplex theater is a dead idea. In today's world with DVD and internet the draw to a theater has been severely cut. Only a very new release will draw a crowd and you don't need 18 screens for that. It went from having 1 large screen with lots of comfortable seating to multiple screens with smaller tightly packed seating which was fine if you think on the movie audience that went to see movies.
Think on the 50s and 60's, single screen theaters, but movies came out only in theaters and stayed for weeks. The only option you had was to wait for it to come to TV. View the 70's and 80's, they started multiple screens to pull in more movie goers that wanted to see different movies, they started making the theater smaller because the crowds were split on which movie they were going to see and didn't need as many seats, along with movies on VCR, you didn't have to go to the theater to see a movie.
The 90's was the beginning of the downfall for theaters, DVD, internet, downloads, blockbuster, who needed to go to a theater to see a movie. Even look at blockbuster and other movie rental places, they are hurting bad from internet and Netflicks. As more in home demand services are created the Movie theater will die on the vine, except for only the newest releases available no where else.
I think a throwback to the older grand large single screen theater might be a good fit for today's new release movie goer. As long as you can provide a good enjoyable atmosphere. I'm thinking a place with enforced quiet, a cell phone scrambler or signal blocking built into the walls. Reduced infomercials and previews before the actual movie. Add in great sound system, lighting, and anything else technical that enhances the movie like 3D.
In today's market the number of people going to see a movie is at a premium and creating a good movie going experience could draw a crowd. Every time I hear of a person with a complaint about going to see a movie its about noise and distractions,commercials before the movie, the condition of the theater, quality of service, and prices.
I think the time of the huge multiplex is gone, time for a smaller and better theater to replace them.
