Query: WHAT IS THAT ?

It was one of the worst movies if not the worst,I've ever seen.Boredom and perversy at the uttermost level.It's not to say that "Spader" and "Gyllenhaal" are unimpressive.Indeed,they both perform excellent acting and they would be extolled if they've starred in somethink better.But purchasing and watching this movie is simply waste of time and money.I rue the day I bought it.
