Just found this website the other day, and its a hoot:

Basically, our intrepid reviewer is spending a year going over very, very bad films, and offering his hilarious insights into them.

Was particularly amused by the Roman Polanski (yeah, that guy) forgotten film What?  Until that review, I had never heard of the film.  Sounds...uh...strange.

The other one I would point you out to (but, please, feel free to read through them all!) is the Steven Seagal turkey On Deadly Ground.  I actually paid money back in 1994 to see that one in the theaters when it was released (it must have been a fairly boring day and the cinemas must not have been showing much, as I was never a particularly big fan of Mr. Seagal and, other than the much more critically accepted/audience-approved Under Siege, these are the only two films of his I ever saw of in the theaters).

On Deadly Ground has to be one of the worst "action" films ever.  I put the word "action" in quotes because truly it seemed Mr. Seagal (who directed as well as starred in this film) seemed intent on making some kind of larger spiritual message while kicking all kinds of ass.  Michael Caine, who I usually absolutely love, is horrible in this film as the villain, an oil man who wants to pollute a pristine Alaskan bay (or somesuch) with his oil drills.  So, to prevent that, our hero blows the whole thing sky high, no doubt ensuring the bay is polluted for years to come.

And, even more hilarious/sad...check out the fact that despite numerous fist and gun fights, no one lays even one fist on Steven Seagal.  Not once!  It's amazing the man didn't walk on water at some point in the film, as well...

For the masochists out there, here's the trailer to On Deadly Ground:
