I don't know what's wrong with the critics on IMDB. My suspicion is that many of them don't like horror, especially when blood and guts are involved. Therefore, they rate many of these films much lower than they should be rated. Thus is the case with Pet Sematary 2. Director Mary Lambert gives us a second helping that goes beyond the Stephen King novel. This time out Richard Outten provides the screenplay, upping the violence and gore in place of Stephen King's more subtle approach. This is not necessarily a bad thing, it's just different. Personally, I think it's harder to do what the first film delivers, but the sequel is a powerful film to watch nonetheless.
In addition to Mary Lambert's direction, the film's other strong point is the cast. Edward Furlong [Terminator 2, Detroit Rock City] is dynamite as Jeff Matthews, a young man who experienced the horrific death of his mother. Anthony Edwards [E.R.] also does a great job as his father. But the real force of nature in this film is Clancy Brown [Highlander, The Shawshank Redemption] who plays Sheriff Gus Gilbert. His manic energy in Pet Sematary 2 is a joy to watch. He definitely provides most of the squirm-worthy moments in the film.
If you haven't seen this one, PLEASE give it a chance. It is a worthy successor to the original.
RATING: Very Good.
