Sometimes you just need the first three seconds of a movie to already know this is going to be bad. A Killer Upstairs is one of those movies. They for sure didn't try to hide it was a tv movie. From the first seconds you get that bad image, that bad music and sound, that lousy acting, that are typical for tv movies. I only watched it because there was a supposed mystery but everything is so predictable it isn't funny anymore. I exactly knew what happened after twenty minutes so no surprise there. The reason I gave it three and not one star is the fact that I laughed a lot and so had a little bit of joy after all. I laughed because the acting is so bad you wonder how the hell those people made it into cinema. All shots are so cliché it becomes funny after a while. It's really bad though, but funny because it's so bad. The music or sound effects that should create a mysterious ambiance are also laughable, the typical sounds of a bad tv movie, in other words the obliged and typical bad piano music. Tracy Nelson, the supposed star of the movie, has her eternal same stupid facial expression for every scene, and that's most likely the reason why she only appears in stinkers.
