A few of the features were out, it's hard to beat the theme and A/V on it is very cool (INMHO).
My unsolicited comment would be the fact that the big 27 LCD screen was a mirror. You could so much more atmospherically could be done with different content on the big screen. Such as shock scares that dare you to look away from the playfield screen.
You could use the playfield LCD to direct you using the motion scanner to the correct ramp as a backup to the playfield LCD lighting.
