Having watched the entire film to see how it ends I can only say the film started off lousy and only progressed downward from an already lousy beginning. I don't care if the actors/actresses agreed to work for free, and the director picked up this script from the "Buy 1 and get 3 scripts free" bin this is just so boring that I cannot pick out even one scene where the dialogue was worthy to be edited in.
Who would even accept responsibility for putting their career ending name to this piece of junk? The film genre is listed as a Thriller much like the (1987) Fatal Attraction was which includes a love triangle that goes terribly wrong where the innocent and unsuspecting spouse is threatened by the unscrupulous scorned third party lover. Sound familiar? Well "Infidelity In Suburbia" is the end result of one person watching the original (1987) Fatal Attraction, and passing the film content by word of mouth from a first person 1 through person 1,000 and what you have left of a half decent film is this diluted piece of junk.
The ending if I told you what happened, would not be considered a spoiler, because the entire film is spoiled from beginning to end. After investing 90 minutes just to watch a terrible ending that I would rather have washed the dinner dishes and thrown out the garbage instead of wasting my time watching this garbage.
I give it two thumbs down because I only have two thumbs.
