Don't let your experience at the museum get you down. I don't think it's comparable to tastes in our hobby. Dioramas are very popular. If you ever get to a show, whether IPMS or otherwise, you can see the work that some modelers do. And there are clubs, websites, and social media groups devoted to dioramas. And if you look beyond the West, to Japan, especially, and other countries in Asia, you'll see that the genre is alive and kicking.
