a with most prison movie and the setting be merely a vehicle for tell the story . prison ain not like that while talk to a couple con and ex con and or even and god forbid and do a little research from print material and would really go a long way . that say and if this movie wasn not so poorly act and mis cast and this might have be more watchable and because the plot be interesting enough and explore male role and male sexuality . the problem be in the act it dreadful . and the mi casting of the antagonist it be impossible to suspend disbelief enough believe he a big bad sexual predator who could possibly over power the protagonist and who be bulky and more butch and and more physically impose . i suspect the main culprit for these flaw be simply the era . i be sure in 1971 it be impossible to find more qualified actor who would touch this kind of subject matter with a ten foot pole and for fear of torpedo their career . time have certainly change since then . a good prison fable about male sexuality and male relationship be the hbo series oz . we have come a long way and baby .
