I love this video, too.
It is not only very impressive and well made by its own rights - I thougth it was very toung in cheeks, when I first saw it. Does anybody remember the public outcry, when the trailer before this one went live? Despite the fact that it was clearly a (well made) teaser film, so many people complained about its "missleading content" and "false advertising" due to its fast cuts and high-speed combat scenes.
I laughed so hard, when I watched this slow-mo trailer and thought to myself: "Well payed, FD, well played!"
But, as mentioned above: even if there was no irony involved at all, the trailer is awesome and deserves all praise!
