My 3 year old seems to like it, the Dinosaurs are fun, but even she got bored seeing the same handful of robotic dinosaurs after the 3rd trip to PSC. Some exhibits are broken or don't work well interactively. Overpriced cafe. Layout of the buildings awkward and can really confuse a first time visitor. Overpriced parking.
Butterfly exhibit is good, but again, after 3 trips with my toddler there even that gets a bit dull.
The lines on a sunny day are terrible, and even members who just want to go to the PSC and not buy any IMAX show tickets have to stand in long lines with folks who are buying IMAX tickets.
