I have to disagree with the comment above from Mike Washen. Indeed, the storyline of both movies is similar for the first part of the movie (no complaints so far), but the second part of the originals movie is more believable IMHO. The original has only one real special effect but this does not mean that the movie isn't scary. Especially due to this lack of special effects a better thrill is created al throughout the movie. One sees just enough to get scared. The originals story builds up a tad more slowly which gives a better story overall. If you are going for special effects, take the remake. If you like to see all 4 movies and like a scary experience overall take the original.
