Reanimator really does animate. Cool.

Re-animator is a 1985 cult horror film and it has achieved his status for a few very good reasons, there is a ton of blood and severed body parts and a scene involving a cat that will leave some viewers slightly queasy.  If an upset stomach is your thing while simultaneously holding an erection, you've found home, although the erection via vi boobs, doesn't come till the end of the movie.  

The premise is that a medical student discovers an elixir to bring back to life dead tissue, thus reanimating the body.  He recruits his roommate to help him.  The bodies don't react well to be woken up from death (the book is excellent in this area).  A few murders later and a man ends up with his head in a suitcase and his headless body carrying it around.

The script is on the low side of average but no one cares.  This movie is about blood.  The script writers are like tissue paper at a masturbation party.  There is a lot of blood and it drips, splatters, and gushes.  The makeup is sometimes laughably bad.  The acting is okay except for Jeffery Combs, the mad scientist.  His performance was amazing; angry, contemptuous, and with a wicked sneer.  He deserves props.  ::::Props to Jeffery::::      

If you like campy horror films, then here you go.  My only complaint, not enough blood.
PS  Watch for the fourth installment House of Re-animator.
