Aside from things that Sea Life Aquarium cannot control (strollers in the way, morbidly obese blocking exhibits talking while a crowd of children are trying to look at them, etc) the aquarium is awesome. My daughter and nephew had a blast. A ton of great exhibits, decently priced admission (currently $18 for adults), and a knowledgeable staff.
And for you out there expecting this to be some world class aquarium, get real. It is in a shopping mall, why would you expect it to be?
For what it is, its really great. I would recommend this to anyone with kids as something to kill a few hours.
