Over the decades, I've liked a wide variety of movies from almost all genres. Back in the 1970s and 80s, I was a connoisseur of kung fu and modern-day action movies from Hong Kong and Taiwan, which played in local "grindhouse" theaters dubbed in English, and I also used to watch many more of them in subtitled form, at the local Chinese and Vietnamese-owned theaters. From the mid-80s on, I watched them when I lived in Taiwan.
Of course, great fight scenes have been made everywhere, in many genres. Personally, I don't give a darn if the fight scenes are 'realistic' or not; even the most realistic-looking fight scene in a movie is still fake. I care about whether I'm entertained or not. Just like my favorite Western movie is The Good, The Bad & The Ugly, but nobody would believe that the gunfights reflect reality.
In some fight scenes, the choreography is elevated to the level of a true art form. I cannot say what my one favorite fight scene is, because there are literally hundreds to choose from. However, for my first post, I've chosen this final fight scene from the 1984 Hong Kong action-comedy Wheels On Meals, which was filmed in Spain. A young, peak-era Jackie Chan vs former undefeated world kickboxing champion (and one of my boyhood heroes), Benny "The Jet" Urquidez. Directed by, co-starring, and action-choreographed by Sammo Hung (Jackie's elder classmate, also seen in part of a comedic fencing scene), the choreography, pacing, camera angles, complexity, and "timing" are perfect. Very few directors anywhere, in any genre, could insert comedy into serious scenes (and vice versa) like Sammo Hung did. IMO, it outdoes the classic Bruce Lee/Chuck Norris fight in Way Of The Dragon:
