I give the coaster 3 stars, my boys give it 5 stars, so that's my reasoning for giving 4 stars.
My boys LOVE Cobra over at Six Flags Discovery Kingdom. Jaguar is very similar except that the track is very high, which kind of freaked them out. While there are no huge drops, the height concerned them.
The coaster has some great turns, a great straight away that picks up some speed, and some great views of the area.
I think the best part of the attraction is the well themed queue. Not as great as say Indiana Jones over at Disneyland, but it definitely is fun to look at.
