For me, the beauty of this ride is that it really rounds off the experience you get from going to Magic Mountain in a much more exciting way. You have the biggest loop in the world with Full Throttle. An insane ride with X2. A giant drop with Goliath. A backwards 100mph launch with Superman. A flying coaster above the park with Tatsu. A 400 Foot drop tower with Lex Luthor. Batman for the suspended looper. Ninja, Revolution, Gold rusher, and Apocalypse for people looking for "tamer" rides. Viper, Riddler, and Scream for tons of loops. And finally the wacky airtime machine of Twisted Colossus, with an awesome racing element.
So does that make it a turning point for the park? Probably not. But it's really good where it is now with its lineup of coasters. Now all it really needs is a focus on general park improvements like we all hope. But they might not find that completely necessary.
