The Ranger is a VERY fun experience.
It fits the ride's description, and marketing well, just the theming is a bit off.
If going upside is your thing (it is for me :D), then the Ranger is guaranteed to give you some cool forces, especially when it holds you upside down for a bit.
The restraints are VERY painful. The waist restraint is very tight, and can be very uncomfortable.
The Ranger has a good ride time, taking you through backwards and forward cycles.
The storyline is better than the Hair Raiser. Pretty much the storyline is you are an astronaut, going around the moon. The ride contains cool theming too.
The Ranger is in very good condition, only making very nerve-wrecking screeches every now and then. The paint job is looking good too.
The line length goes down very quickly, as the Ranger can hold a lot of people at a time.
