deanloves This is one of the best movies I have seen this year. It starts off with a romantic couple who witness a suicide or possible murder. There are lots of turns and twists in the movie and will have you on the edge of your seat. Many facets of the movie resemble "real life".Is the lone hunter a gun nut with a dark side? Or a creative computer programmer, who is losing his mind caught up in his own virtual fantasy world. Playing mindless violent video games? What is real and what isn't? The story is original and will keep you guessing right to the end. Afterwards I was thinking about many aspects of the movie. It reminded me of a classic Alfred Hitchcock suspense thriller.The movie title says it all. IS he losing his mind or has he been pushed over the edge by his jealous rage?
