Input: Consider Input: Review: I enjoyed this movie,and after watching it,it made me wonder just how many 'Caitlin Rose's' exist in the world.How many other girls have been subjected to this sort of sexual abuse,and torment by classmates and have been too frightened to open their mouth about it? Just how threatening and cruel can teenagers be towards one another,because as this film demonstrates,who's right is not foremost important,its who is popular,and feared which manipulates the minds of youths,and influences them to allow this sort of immorality to happen.Tiffani Amber Thiessen gives a powerful performance as the rape victim,and Brian Austin Green is convincing as the guy torn between the girl he thought he loved,and his best friend.This is the kind of film that doesn't get the exposure it deserves.Remarkable,and brilliant,too good to be just a film made for TV. Question: is it a positive review?

Output: yes


Input: Consider Input: Review: Grand Canyon is a very strange bird. It's a completely unique urban piece, where relating the entire plot would fail to convey much.It's central theme seems to be the inherent uncertainty life holds for people of every race, background and station. But to proclaim that THE theme of the film would be to horribly understate its scope. Similarly, to pigeonhole it in a particular genre is futile.The film has volumes to say, though likely different volumes for every viewer, and says it all in such a non-preachy way from so many angles, that in the end, i can't even define its central message for myself.Nevertheless, it does it's business with such laser precision; every prop, line of dialog, and bar of background music contributing to it's pervasive mood and powerful message, that i'm pleasantly surprised, and come away very thoughtful after every viewing. Still it doesn't feel at all stuffy. A sparkling film with a great cast and everything working. Question: is it a positive review?

Output: yes


Input: Consider Input: Review: This supernatural Peter Weir thriller is truly one of the most haunting and fascinating movies ever seen. Richard Chamberlain does his best performance here as the Australian lawyer who defends a group of young Aborigins accused of murder. As he gets closer on the case, he discovers more about the main defendant, Chris, and not least about himself. Chris tells him that he is a Mulkurul, which appear to be a race of supernatural beings that lived in Australia thousands of years ago. At the same time, extraordinary high rainfall seems to confirm the Aboriginal prophecy of the coming of the LAST WAVE, the one that will drown the world.The dream sequences and the supernatural effects enhance this movie and make it a spectacular experience. Olivia Hamnett and David Gulpilil are solid in the supporting roles, as well as the chap with the difficult name who plays Charlie, the old Aborigin who can turn into an owl. The climax and the ending don't disappoint, in contrast to many other supernatural thrillers who fall flat after a promising hour or so. However, this can not be called a pure thriller. It is a drama as well and talks about spirituality and spiritual identity in the modern world. A masterful work by Peter Weir, the master of visually stunning dramas.
