An opinion is only as good as how well you can defend it. You can think Marley and Me is the best movie ever made, but if you can't articulate why it is the greatest movie ever made, what you have said is essentially meaningless. You have to support that opinion with facts, such as the subject matter of the film, its formal qualties, the actors' performances, etc.
Not all opinions are equal. Those who can defend their opinions with arguments that are more than just, "Oh but the doggy is so cute!" have greater say when it comes to whether or not a film is good or bad. Likewise, a good argument is something you can respond to, and criticize, and counter with your own argument. That is one of the only ways to reliably gauge whether a movie is good or bad, to be able to explain why it is good or bad.
Its like someone saying they don't see any problem with society allowing people to murder each other. They are more than entitled to their opinion, but that does not mean that their opinion is correct or that they have any idea what they are talking about.
We had two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half full of cocaine, a whole galaxy of multi-colored uppers, downers, screamers, laughers…Also a quart of tequila, a quart of rum, a case of beer, a pint of raw ether and two dozen amyls. The only thing that really worried me was the ether. There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. –Raoul Duke
It is hard to shed anything but crocodile tears over White House speechwriter Patrick Buchanan's tragic analysis of the Nixon debacle. "It's like Sisyphus," he said. "We rolled the rock all the way up the mountain...and it rolled right back down on us...." Neither Sisyphus nor the commander of the Light Brigade nor Pat Buchanan had the time or any real inclination to question what they were doing...a martyr, to the bitter end, to a "flawed" cause and a narrow, atavistic concept of conservative politics that has done more damage to itself and the country in less than six years than its liberal enemies could have done in two or three decades. -Hunter S. Thompson
