There's a disappointing lack of people being cut in half and the lightsabre impact effects could use more oomph, but this video featuring a Jedi Ninja showdown by Team 2X is worth a look.
Now, the question of how/why ninjas, Jedi and Sith would all be in a warehouse on Earth is not answered. But the fight choreography's good enough to make you gloss over such questions. Best of all, I love whiplash-inducing reversal of tone at the end of this clip. It reminds you that all this stuff -- even as executed at the highest professional levels -- can be boiled down to really fancy LARPing.
