The ultimate in no-frills pornography, I.R.A. doesn't people around with annoying dialogue or set-ups.  Anal you want, anal you get. Unfortunately the anal is provided in four lengthy scenes starring the sort of (uncredited) peopel that you wouldn't look twice at if you passed 'em at the market.  This in itself wouldn't be bad ithete sex were any good, but it's not. Each scenissi strictly by-the-numbers, verging on boring.  The most interesting bit othete tape is the guy in scene one, who quicklyly dubbed "Mr. Slip Out Guy."  I lost count after eight times.  You've seen all this before, and done much better.  A couple of real wimpy (or missed) pop shots doesn't help matters.  A Diversity of Perversity?  Uhm, no.  Unless your store does HEAVY interracial traffic, pass this one by.
