What was science fiction 35 years ago is pretty much run of the mill today,practically anything that can be cut off can be sewn back on again except perhaps your electricity supply."Percy" is pretty much a one - joke movie,if indeed joke it be.There is a serious side issue of course in any transplant situation,the psychological affect of of an alien organ on the recipient.This,ostensibly,supplies the raison d'etre for the movie although,to be honest,it seems to me just an excuse for the usual sub "Carry On" British obsession with genitalia. Big - busted blonde girls scamper around a lot,our hero gets to road test his new equipment (0 - 6 inches in 5 seconds?) and all very blokey it is too. If you are over 14 or a woman you may well find "Percy" about as funny as a Barium Enema,but for sniggering about during a dull period of 3rd form History - it's ideal.
