"The Good, the Bad, and the Weird" is also the title of an excellent Korean movie from 2008:

This was the first thing the title made me think of and I second the recommendation. Watched it for the first time last year and it's the most fun I've had watching a movie in a long time. Soundtrack was also notably excellent, both music and sound effects.

Strange. Usually it's either excellent movie xor Korean movie.

You have no idea. Since the revolution, Korean movies were at the forefront of international movies. The blast lasted from 1999 to about 2013 with some occasional masterpieces thereafter. https://koreanfilm.org/
