I agree. Always thought that Chiller looked like an awesome ride, but it was gone by the time I was able to get to the park.
I know both Mr. Freezes, and the Chiller had awful opening year problems, but why was Six Flags able to turn the other two into reliable coasters, but never The Chiller??
The Chiller had issues with dueling, when both the trains launched at the same time it would put a lot of stress on the power grid (which is why they ran staggered and later only the robin side). The Chiller also had issues with LIMs burning out and train issues with the zero-g roll. If you want to read more look at the GAdv History page.

Wow, that was in interesting read. I never knew the ride was such a nightmare for the park.
