Honestly I'm on board with the fix the guns and the ride is fine gang. It works well for kids and not terrible for adults imo. Not that I would be opposed to a dark ride that moves quicker and is a little more tough for adults.
The most annoying thing with boo blasters is that you can, one-time, get a gun that works and get 3,000+ points and the next time get a gun that doesn't work at all or one that works only half of the time and you get like 1,500 points.
