When a Stranger Calls (DVD, 2006)

The original "When a Stranger Calls" (starring the multi-faceted Carol Kane) is a classic horror film for many reasons, including: (a) superb acting, (b) superb directing, and (c) the perfect balance between pure horror and psychological suspense. The storyline is interesting and many things happen to keep the plot constantly moving forward. It's also an intelligent movie, requiring the audience to figure things out and make its own discoveries.
All this said, the re-make does not do it justice. Simon West took the first fifteen minutes of the original (when Carol Kane is babysitting, which is simply the introduction to the film) and stretched them out to create an entire movie. The scenes are monotonous and repetitive, and the acting isn't very good. Also, the character of the killer was very much toned down; in fact, we never really know his motivation or get a glimpse into his psyche (as was done extremely well in the original version). This makes him unrealistic, underdeveloped, and not very frightening.
Perhaps the lack of characterization and graphic violence may be explained due to the fact that this re-make was made for a younger audience (probably under 16 years of age). In any case, this is clearly not a mature horror film. It's lacking in substance, depth, and innovation.
If you're a fan of good old horror movies (i.e. Last House on the Left, Evil Dead, Psycho, The Shining, Suspiria, etc), then I would HIGHLY recommend the original version of this movie instead of the re-make.
