Review: I thought this was a very good movie. It would have been nice to have seen a little more into the movie about the 2 sisters knowing about each liking the same boy before he was killed off. I'm sure if the movie had been done this way there would have been a very different ending, that's why this made this move such a good movie. It shows that no matter what happens in your life with your siblings that you can always get thru it and that if it's 2 sisters dealing with a boy, (the same boy) that working thru the pain and hurt makes things to seem better and easier to work out between the 2 of them. It's nice to see love stories that have a terrible thing to happen in someone's life that you can still get thru it become even closer after its over. I really enjoyed watching this movie, and I still do now when it comes on. I seem to find myself watching it every time it comes on. It would have been nice if there would have been a part 2 for this movie, maybe having the older sister to come up and have his baby, this would really have made a great finish to the story since he died, this way it would keep him alive even though he's dead. Question: is it a positive review?

Ex Output:
yes

Review: This film takes you on one family's impossible journey, and makes you feel every step of their odyssey. Beautifully acted and photographed, heartbreakingly real. Its last line, with its wistful hope, is one of the more powerful in memory. Question: is it a positive review?

yes

Review: . . . or type on a computer keyboard, they'd probably give this eponymous film a rating of "10." After all, no elephants are shown being killed during the movie; it is not even implied that any are hurt. To the contrary, the master of ELEPHANT WALK, John Wiley (Peter Finch), complains that he cannot shoot any of the pachyderms--no matter how menacing--without a permit from the government (and his tone suggests such permits are not within the realm of probability). Furthermore, the elements conspire--in the form of an unusual drought and a human cholera epidemic--to leave the Wiley plantation house vulnerable to total destruction by the Elephant People (as the natives dub them) to close the story. If you happen to see the current release EARTH, you'll detect the Elephant People are faring less well today. Question: is it a negative review?

Ex Output:

no
