Whats the difference between Superman and Bizarro at Six Flags New England?

Honestly, they are quite similar. But, the "Superman" ride that you're referring to is actually the Batman ride. Last friday, I went on both of them, and I liked Bizarro so much better. It's a lot more thrilling, and you drop from a lot higher than you do on the Batman ride. It is also a little longer, and is well worth the wait. You feel weightless at times, and there is a lot more excitement to it. The Batman ride is also very fun, but there are more corkscrews and loop-de-loops on it that will hurt your neck if you aren't careful. The Mind Eraser is also very fun, but it does hurt your neck or head with all of the twisting and turning. Hope I helped!!
