Oh yeah, I must have missed that. This thread moves way too fast.
But yeah, I don't care that they're not accurate to "teh source" but it was something I noticed instantly. My nerdy, **** retentive mind was like, "THOSE AREN'T THE STEPS THAT LEAD UP TO THE COMPUTER CONSOLE". Regardless, I still love the idea though. Like you said, they had to be implemented that way and I love that they don't just stop on the steps he's on but spiral around the stalagmite. Besides, who knows what other facilities, access points and command centers he had in the cave. Those bats under neath the platform are also a really nice touch. I think this is the best possible interpretation of the Batcave that they could have done. Seeing as how the '89 Batcave is my favorite of the 7 film lairs, I really dig the choice.
That Cathedral concept you mentioned would have been cool though. I really want a proper, bloodied Batman. The ketchup mouth on the Hot Toys figure just doesn't cut it. They could have had your idea and maybe have added Vicki's shoe or something on the wooden landing.
