Why as many good reviews ? I thought this was a badly done cliché...the acting apart from Lucas the psychopath was made-for-tv but worse in fact. The story briefly believable at first, then unconvincing and then ridiculous. Perfect downward spiral and the ending eh? Some lives lost. Others ruined. Very uplifting. I mean if the teacher turned out to be a real deviant, that might have been the twist this needed to make it worth the time spent. Someone entitled their review "I want my 87 minutes back". That says it all.
