(1.) Cheesy acting and script. The dialogue sounded like it came from a high school drama class project. Quality acting credits? As is typical in these movies it is nearly invisible. Lots of TV videos, shorts or such movie classics as "She Alien", "Savage Island", "Return of the Killer Shrews", "Pimp Bulies", "Swamp Shark".
(2.) Creating a lot of confusing, is it a dream or is it real, subplots only works with a quality script, plot and acting otherwise it's just arrogant look at clever me, "I can confuse you." writing and directing.
(3.) Storyline: Some homeless guy bumps his shopping cart into some wealthy chick's shopping cart in the middle of a mostly empty parking lot. "Whoops, sorry, I didn't see you. How clumsy of me." Within the next 10 minutes he's recruited to come live with her and her husband and, oh, also kill him. But she doesn't know that the husband hired him as a cheap private eye to check on her. To make this a love quadrangle, is another boyfriend, who has been recruited by the wife to steal her husband's prized painting and sell it to some accent laden crook in a warehouse for 5 million - sure! Private eye shoots all the people involved in the painting heist, steals the money, and for some bizarre reason decides to just put one bullet into the gun afterwards, then spins the chamber and walks around in broad daylight and the rest of the movie like it's fully loaded. Does not make sense storytelling, does not equate with good storytelling. The final result is, quite implausibly, the wife lives and private eye dies. Anybody else that appeared in the movie is just forgotten about.
