Look, the place is OLD. But my kids (6, 4 & 3) loved it and are already asking when they can go back. It's not a huge park, either, so you can do it in half a day. And the admission price is low. So as long as the kids enjoy it . . . I mean, I wouldn't make some big drive for it (we live about 40 minutes away), it's not worth that, but for the price, it's not bad. Limited food options, though, so I wouldn't recommend planning to eat there.
Also note there are a number of rides that kids can go on but adults CANNOT. So be sure your kids are able and willing to ride alone in some cases.
