I'm not going to lie - there is certainly a cheesiness factor about the town of Wamego. However, the whole town has embraced Oz and made it their own.
The museum itself is charming. There is memorabilia of all kinds stemming from the books, plays, movies, and music inspired by Oz. While the museum doesn't have some of the interactive gadgets more well-funded public museums have, it does a great job of grouping pieces appropriately. I wouldn't say that it's a great place for small children, but kids old enough to read would certainly find enough to keep them entertained. Even if you're just passing through, be sure to stop and visit the shop, and compare your foot- and hand-prints with those of the munchkins' impressions just outside the museum.
The museum takes about an hour to visit - unless you stay to watch the whole movie - but there are a few other things in the town that contribute to the Oz experience. If you're lucky enough to be in the area in the fall, the museum hosts Oztoberfest - a quaint little street festival of costumed characters, wine-tasting, vendors, and autographs by actors/munchkins from the film.
I really enjoyed the Oz Museum. I wouldn't plan to make it my ultimate destination, but if you're in the area and looking for a charming distraction, the Oz Museum is the place.
