While “once upon a time in Hollywood” ISN’T a western exactly, do you as a western fan find any appreciation/entertainment value because of the western elements?

Like no it’s not a western in of itself, but there’s a subplot about making a western film, one of the main characters has an entire career centering around making spaghetti westerns, the Spahn ranch setting etc. I have no idea how this post is gonna go over given this is kinda atypical but let’s have a discussion lol. Oh and sorry for the wordy title, I just want people to understand why it’s here.
