PROBLEM: Review: "Heartland" is a wonderful depiction of what it was really like to live on the frontier. The hard work and individual strength that were needed to survive the hardships of the climate and the lack of medical care are blended with the camaraderie and the interdependence of the settlers. The drama was especially meaningful because the story is based on the diaries of real people whose descendants still live there. It was also nice to see the west inhabited by real people. No one was glamorous or looked as if they had just spent a session with the makeup or costume department. Conchatta Ferrell is just wonderful. She is an example of the strong, persevering people who came to Wyoming in the early 20th century and let no hardship stand in their way of a new life in a new land. Question: is it a negative review?

SOLUTION: no

PROBLEM: Review: Family problems abound in real life and that is what this movie is about. Love can hold the members together through out the ordeals and trials and that is what this movie is about. One man, Daddy, has the maturity and fortitude to sustain the family in the face of adversity. The kids grow up,one all be it, in the hard way, to realize that no matter how old they or a parent is, the parent still loves their children and are willing to provide them a cushion when they fall. ALL the actors portraying their characters did outstanding performances. Yes, I shed a tear along the way knowing I had had similar experiences both as a young adult and later as a parent. This true to life is one which every young adult, and parent, would do well to see, although some will not realize it until they too are parents. A must see for those who care about their families. Question: is it a negative review?

SOLUTION: no

PROBLEM: Review: "I Am Curious: Yellow" is a risible and pretentious steaming pile. It doesn't matter what one's political views are because this film can hardly be taken seriously on any level. As for the claim that frontal male nudity is an automatic NC-17, that isn't true. I've seen R-rated films with male nudity. Granted, they only offer some fleeting views, but where are the R-rated films with gaping vulvas and flapping labia? Nowhere, because they don't exist. The same goes for those crappy cable shows: schlongs swinging in the breeze but not a clitoris in sight. And those pretentious indie movies like The Brown Bunny, in which we're treated to the site of Vincent Gallo's throbbing johnson, but not a trace of pink visible on Chloe Sevigny. Before crying (or implying) "double-standard" in matters of nudity, the mentally obtuse should take into account one unavoidably obvious anatomical difference between men and women: there are no genitals on display when actresses appears nude, and the same cannot be said for a man. In fact, you generally won't see female genitals in an American film in anything short of porn or explicit erotica. This alleged double-standard is less a double standard than an admittedly depressing ability to come to terms culturally with the insides of women's bodies. Question: is it a negative review?

SOLUTION:
yes
