Which Superman?
(I'll just assume that you've been on Superman: The Escape at SFMM)
Tatsu is closer to Batman: The Ride - same manufacturer, with a great emphasis on flying.
The coaster sits high on the hill, and the seats fold up against the track, putting riders in prone position - it feels like being Superman.
Tatsu has excellent pacing, the biggest element of the ride isn't until just before the end. Depending on your position on the train, it has a very different "feel" - the back row is almost too intense for marathon riding, while the front row is swoopy and more visually amazing.
Tatsu is the best steel coaster in California, imho (we don't have that great of a choice, in the grand scheme of things), and an excellent addition to SFMM's coaster collection.
