Any room in the center of the temple except the Room of the Mandarin Hand..it was pretty good. As well as the Room of the Fallen Columns, it had an objective that was reasonable.
The Heart Room--Pointless, just hit an actuator. I would actually preffered Medusa's Lair in the first season. And besides, with such an easy objective, people still had no idea what to do (take Kim for an example...)
Medusa's Lair--Way too time-consuming, and took away so many dreams of Legends contestants. Also, when I was young, the screams from the snakes being put in and the pink eyes and roar when the objective was completed made me really scared when I was young.
The Chamber of the Sacred Markers--Too time-consuming, finding markers and then matching them up, they could be anywhere on the walls, not to mention the scariness of a temple guard appearing in the door to the King's Storeroom.
More? OK, here we go....
The Room of the Golden Idols--No one hugged an idol anyway, so it was pretty pointless. They should have hugged an idol no matter what.
The Treasure Room--This is by far, the worst room ever in the whole show. It was basically a second Heart Room in the temple.
Any room in the top-left corner that had an elevator--There could be at least be an objective to open a door covering the elevator or something. Also, the elevator should have been faster!
Whoo.....I hate a lot of rooms.
