Black Sheep

This movie is brilliant. Killer sheep. Need I say more? Two bothers inherit a sheep farm. One brother wants out of the family business. The other brother buys out the uninterested brother and is involved in some genetic mutations on sheep. The sheep begin to kill people and the people they bite turn into killer sheep as well. So after a while, the countryside is covered in killer sheep. The older brother and his team have developed an antivirus for this mutation, but the brother ends up being a giant sheep monster instead. As usual the good guys win, but it's still got some funny lines, and hilarious bloody sheep special effects. Don't get this one mixed up with the Chris Farley movie of the same title.
