The world-leading dinosaur exhibit is amazing, no matter what your age, and there are numerous other areas to be discovered that will keep you entertained for hours (the gemstones, meteorites, Rose Space center, Millstein Hall of Ocean life, etc...). Some of the exhibits are dated, but I woudn't change them - they give a glimpse of how the museum evolved over the decades and have essentially become ""classic"". There's plenty of ""new"" to see as well. While it can get a little pricey if you are buying for the day, the family membership is an absolute bargain for frequent visitors and allows you to completely avoid the ticket lines. And, contrary to some earlier comments, the cafeteria is fairly priced (this is NY folks) and has a number of options for kids and adults.
Pros: Dinosaurs!!!, Rose Space Center, Dinosaurs!!!
Cons: Parking prices
