although i in general enjoy the "sugarwalls" series, i was very disappointed with this particular flick.
the most distracting thing for me was the terrible music choices. the loops were very short -- to maximize boredom -- and many were done in a minor key making the music more depressing than anything. if the budget didn't allow for better music, i would have much preferred that the music be left out since the performers were making far more interesting sounds.
this is the first movie i've seen from this director, and i'm not impressed. although he used many of the "standard" shots and poses, some how he managed to do so in a way that wasn't very exciting or interesting. he stayed with some poses for way too long, and he also looped in the same footage repeatedly. (i know that's a pretty common practice, but the best directors don't seem to need to do that, especially showing the same scene 3 or more times in fairly rapid succession.)
i wasn't familiar with any of the actresses, but none of their performances was exciting enough to make me want to find other movies in which they have acted.
bottom line: imho, you'll have a better time if you select another one of the movies from this series.
