But see that the whole point it was a terrible movie in some parts like Arnie being a one man army, but cheesy puns and one liners are what made it great. you kind of proved my point there, without Arnie in it would anyone even know of Commando never mind like it? It was his presence alone in that film which to this day still gives that film its fanbase.
Again yes there both better actors, Stallone as in Copland proved but never got much credit for, also Willis again better actor. But Arnies films werent about dramatic acting but all about the sillyness really which is what made them so lovable. I love Willis and Stallone also the likes of De Niro in Taxi Driver. But the films like Arnie made in the eightys although not as credible in acting terms or there plots still have there place aswell. I love all types of films depends on the mood.
Case in Point: Red Scorpion, another 80's action film with Lundgren in the lead role. Not an awful movie, and certainly more competent than Commando, but entirely forgettable as a decidedly generic action film.
No-one would ever claim that Arnie was a better actor than most, if any, of his contemporary rivals, but he had an undeniable charm that added something to the movies he starred in beyond acting ability, and he always played to that strength.
