I say it's amazing! It's an incredible feat to have been built and still making clean electricity today. Wish there was a bit more about water conservation since the drought has clearly effected Lake Mead. Parking is $10 and there is a power plant tour for $15 ($12 for military). Other than the mines and the turbines, there isn't too much on that tour, but it is very informative if you like engineering, science or architecture. Walking across it and seeing it from the Pat Tillman Memorial Bridge are amazing.
