I rode rode Superman Ultimate Flight at Six Flags Discovery Kingdom for the first time last week. I've been thinking about it every day since then. It is a crazy intense ride that is also breathtaking. Each elements it was surprise and I wanted to know what would come next. I have the feeling it is not loved by the Roller Coaster enthusiast. Maybe I would not enjoy it as much if I have rode hundreds of coasters. If Discovery Kingdom was just down the road, I'd ride Superman Ultimate Flight all the time. It is currently a top 10 coaster for me, but that is not super long. I really want to ride more coasters to build out this list.
