You need to go back a fair way to see it done well: most of the best are in the 1940s swashbucklers. General opinion is that Basil Rathbone was probably the best actor with a sword (although that didn't stop quite a lot of Errol Flynn sword jokes). The duel between the two of them at the end of The Adventures of Robin Hood is a bit silly, and not especially rigorous - but is fantastic to watch. Films nowadays tend to go for either the modernist approach (lots of close-ups and very quick cuts so you can't see what is going on - it means they can use stunt men for everything) or the accurate approach (the fight is over in a few seconds, as most real ones were). The only old-school ones I've seen for ages are the Pirates of the Caribbean ones.
