Although you may not be able to understand what is going on in the show as it is all narrated in Thai, you should be able to appreciate the humour. I certainly found it fascinating to watch as I had never seen a genuine shadow puppet show before. I think these puppet theatres are surviving as they are adapting by putting on performances with contemporary themes. If you want to learn more about this ancient art, then I suggest that you visit the Thai Shadow Puppet Museum in Nakhon Si Thammarat.
