What I find amusing about it is that J-dubs always love to judge "Christendom" for their elaborate churches full of expensive materials and finishes, and biblical imagery on the walls. Yet they fawn over and show off this theatre that is full of all those things.
We were recently touring a historic church in another country with some J-dubs and they were all commenting how freaked out they were over all the bible scenes painted on the walls and . "I'm so glad our Kingdom Halls don't look like this!" I couldn't help myself and finally said, "Actually all these fancy columns and wall murals remind me of the Stanley Theatre." The looks on their faces was priceless. One person offered up a quiet: "Well that's different.", but the whole group suddenly stopped their criticism of Christendom's churches.
If you hung a big crucifix over the stage it would indistinguishable from a lot of big churches out there.
Closest thing the Watchtower has to St. Peter's Basilica.
