It's an interesting list... honestly, none of them are anything I'd recommend for anything other than pure escapism and entertainment... in which case, they're all fun movies. Personally, I'd look to Seven Samurai, Kuro Obi, Twilight Samurai, Hara Kiri etc as my "go-to" list... of course, that does betray my more Japanese-influenced background, as opposed to the article's authors Chinese-arts bent. I think that's been an influence on the choices, really... different arts will have different preferences for films... a BJJ guy might go straight to Red Belt (personally, I was rather ambivalent towards that one...), whereas a Wing Chun guy will go straight to Ip Man (or Ip Man 2). I don't really think you can get a list that "Every Martial Artist Must See"... it assumes there's far more common ground than there actually is.
