I knocked them a star due to cost. It cost $12/person to get in. Just to the bare bones museum - not the planetarium, or any of the side show type things they have going on (rock climbing). So in all, we probably spent $40 (2 admissions plus some of the extras, not the planetarium). :-(
Though, it does rock for their exhibits and galleries of insaneness.
Next time I hope I can enjoy it more because I was awfully consumed in financial woes.
