Also I cannot see how having a sword fight on a rolling wheel can be a poor joke... It's just too... Hilarious!
Actually, the swashbuckling in the movies is one of the things I like least. It is so poorly done.

I know, I am picking nits, but think of it this way: most of us are fairly technically literate. We see computers portrayed in movies, and most of us roll our eyes and laugh (i.e. "Hey! I know this! This is Unix!" from
Jurassic Park). We know what computers can do, and what they look like when they are doing it. Then we see how they are portrayed in movies, and know that it is just wrong.
I fence. I have fenced since college (almost 10 years now). While modern fencing is not meant to be life-or-death, and differs greatly from actual combat, years of training can show you what is possible, and what will get you killed.
Pirates of the Caribbean is way over on one end of the "it will get you killed" spectrum. It may be pretty, but it is no good in a real fight. Perhaps if the movies were better, I might be able to suspend disbelief a bit more, but the movies really aren't that good, and the bad swordplay is hard to ignore.
