re-animator (1985)

aka H. P. Lovecraft's Re-animator.
In this H.P. Lovecraft tale, Herbert West (Jeffrey Combs), is a medical student who has discovered a way of re-animating the dead, using a special serum. After the suspicious death of his professor in Switzerland, West moves to New England and enrolls in a medical school there to continue his research. He immediately argues with his professor, Dr Hill and unwittingly involves another student Dan Cain and his girlfriend in his experiments, with predictable and gory results.
A classic horror-comedy, where all the parts come together, from the actors, the special effect and the script. They all combine to make a film which whizzes by is a blizzard of blood and hysterical set pieces. A must see, as long as you have a strong stomach.
