Quality of the Movie

We all know LMN movies are not going to win any academy awards and they will never have a 100 million dollar budgets, so I try to judge them on there storyline. If there are characters that act out of character, then I will mention that too. This does have a strong reference to Strangers on a Train at first, but like someone had mentioned before it has some good twists in the last quarter of the movie. For an LMN movie it should get an above average rating. But we should all realize that these type of LMN murder mystery movies are like the Italian "Hercules" movies of the 60's and the Chinese "Kung Fu" movies of the 70's. They are all guilty pleasure movies.
