Ho Hum
It's clear the author is going for dramatic effect and action, but most of the action is too slowly paced to be particularly interesting. Venturing a guess, I'd say the author worked very hard on the choreography (which is fairly complex in many cases) and is making the mistake of slowing things down so the viewer "has a chance to see it all". That's what a "slo-mo retake" is for --- show the high-speed shot, then cut to replaying the same take (preferably from a slightly different angle) in slo-mo. Here, it just seems that the characters are practicing their moves.
Beyond that, there's nothing in this trailer that really tells me anything about the five short flicks it's promoting, except that they apparently contain a lot of action scenes...slow-paced, boring action scenes. Pass.
