Velocipastor is so much better than it has any right to be.

Helen Keller vs. Night Wolves has the most hilarious opening song and is the very definition of a B movie.

Super Hybrid is another B movie that has no right to be as good as it is. Highly recommend.

As mentioned in some other comments Poultrygeist: Night of the Chicken Dead is an absolutely ridiculous romp from Troma.
