Never watched the movie and didn’t know about it, but I imagine a lot of castle builders will get this for the medieval-style house!

It does look really nice. I don’t think I will ever advise someone not to buy a nice lego set. However, if you don’t really enjoy the movie, you will probably miss a few of the cool details they put in the build and it might give you a little less pleasure displaying it somewhere. If you still want to go for it, I would put it on your brickwatch list and wait for 35 to 40% discount.
