Saw this film- it was a hilarious mess, akin to "the room" but with a bit more of a vision. Much better trailers than actual movies. The second section was not rehearsed or choreographed at all. I imagine this was more the ego of the director than the steadicam operators. At one point they have to whip from person to person in an argument, and the camera rarely lands in the right place or on the right person.
The movie would have definitely benefited with coverage, and not using steadicam to shoot the majority of it. There's a table section within the club scene where the operator has to do a bunch of unmotivated movements after holding on a wide 2 shot for a couple of minutes, that again, does not work for the scene.
