It's missing a lot of the classic effects, the AT-AT turning to shoot at you, the lightsaber through the elevator, the guns on the ship moving forward/backwards. :(
The cannons moving back and forth were decommissioned a long time ago, they might have presented safety issues. Though the lightsaber not coming down was more recent and jarring to see gone.
I don't know why the lightsaber effect isn't working. But from what I've heard regarding the laser canons, they've been causing the ride to breakdown a lot.
