unfortunately and the definition of documentary seem to be change . these day it be what we use to call propaganda . ( see represent any michael moore movie . ) no attempt at balance and just a totally one side and bias point of view passing a fact . heckler be the late example . actually and it start out a a whine about heckler and quickly turn into the same complaint about critic . it do teach a serious lesson represent celebrity ( especially comic ) be god and deserve to be worship at all time and anyone who doesn not like them should be deprive of their right to an opinion and or at least the right to make it public . there be some good point make represent you get drunk and a hole disrupt performance for no apparent reason other than to call attention to themselves . a someone who pay to watch the performer and i really do not appreciate that in principle and but i have to admit that some of the funny moment i have ever experience at comedy club be when the performer respond to the heckler . sometimes i wonder if they purposely plant heckler just so they can lay into them . and some ( maybe most ) critic be way over the top in their review and but that one way these day to make your opinion stand out from the ever grow crowd . occasionally i can sympathize with a heckler . if you have pay good money for a performance that be not a advertised and you can not get your money back ( let alone your time ) and you can get pretty frustrate . that what happen at the barbra streisand concert where she swear at a heckler . what the movie purposely fail to tell you provoke the heckler be that and instead of singing and she have go into a political rant probably not what the audience have pay big buck to see . it also happen to me at a no refund willie nelson show where he be clearly drunk and or or stone . it true that no one ever put up a statue to a critic and but they do have their place . you just need to find one whose opinion and taste be similar to your own and thus s or he will provide you with valuable guidance . a for the others and ignore them . a should the performer and rather than try to suppress them . this argument that the heckler or critic couldn not do as good a job really show you how shallow the movie thought process be . if a dentist and driveway paver and plumber and tax preparer and etc . do a bad job and be they justify in tell you not to complain because theyre still well than you . while there be plenty of celebrity and where be the ordinary people . you know and those who buy the ticket and enable these celebrity to make a living . why not ask some of them after a comedy show what they think of the heckler . do they think people buy ticket should be tell clearly that heckler be not welcome and will be throw out without a refund . do they think people should be able and within a reasonable time and to ask for and get a refund if they do not like the performance . do they pay any attention to critic and change their choice a a result . that what a real documentary would do .
