If you've never seen this classic (which I'm awaiting on DVD to replace my MGM VHS copy), please DO check it out.  I first saw it in Oxford, Ohio in 1976 at an all-night movie marathon at a tiny Oxford theater that also was shwoing "Dr. Jekyll and Mr. Hyde" and "Mad Love."  ("Freaks" was shown between these other two films. I think my friend and I  got back to his dorm room at 6 am. 

)
"Freaks" is sometimes unsettling, but it makes this gay quasi-liberal even more empathetic to those who have no control over their physical/emotional destiny.  That said, the movie is also very uplifting when one considers that the "underdogs" take responsibility for themselves and "undo" those with undeserved power.
Watch it--and then let's hear what you have to say, please.
