Example Input: Review: ...but I regret having seen it. Since the ratings on IMDb are relatively high (and they must also have been relatively high on Netflix), I guess I put it in my queue because it is advertised as a gentle comedy from the UK, a category that has produced many films I liked immensely. "Saving Grace," on the other hand, falls into the category of laugh-less comedies usually populated by Hollywood movies produced and directed by the talentless. Brenda Blethyn is a capable actress, and I have liked her in other movies. The concept -- a gardener growing marijuana to overcome the penury she finds herself confronting after her husband's death -- does not offend me. Notwithstanding the strenuous efforts on the part of the cast to produce humor, the film falls flat on its face (falling flat on its arse might have been funnier) as far as I and my wife were concerned. Be forewarned, oh gentle reader, not all offbeat British comedies succeed. This one is a dud. Question: is it a negative review?
Example Output: yes

Example Input: Review: I am of "the Christopher Reeve Generation" it is fair to say that he was the best actor to play Superman yet, but that doesn't stop me from enjoying other actors in the role, and George Reeves makes a pretty good bid to knock Chris off the top, though he just barely falls short. That doesn't stop me from enjoying this film, it has a lot going for it. It has all that a movie needs, a plot with beginning, middle, and end, plus all those parts are intelligently written. The film is edgy both in acting and storyline, something a film-noir but with tights. The story is both exciting and meaningful, this is a movie with a message that isn't too preachy. I am still amazed this was shot over 12 days, oh the glory days of Hollywood, when we didn't have to wait 5 years just to see if the movie would fall into development hell... The film is polished and expertly made, directed by Lee "Roll'em" Sholem, best known for directing with both speed and efficiency. It never lets the constraints of technology slow it down, in fact there is some creative things done to create the effect of flight, including putting a camera on a boom on a truck and shooting high and traveling fast to make it look like we are seeing it from Superman's point of view, also a few closeups of George in process work, and a long shot of an animated Superman. This is now available on DVD as an extra feature on the first season of the George Reeves Television series. A DVD worth owning in its own right, the inclusion of the film as its original whole, is icing on the cake.Give Blood Today God Bless! Question: is it a positive review?
Example Output: yes

Example Input: Review: Spoilers.First off, nothing really happened in this movie, other than a woman bleeding inexplicably. Second, it wasn't scary. Third, it had the worst soundtrack of any movie ever. Let me elaborate. The sound was edited by either Beavis or Butthead I'm not sure which, so let's just go with Beavis. The movie gradually gets more and more quiet and the people mumble and mutter, forcing you to turn up the volume (I watched this at home). Then Beavis blasts some really loud sounds with supposedly scary/shocking images, forcing you to quickly lower the volume again. This occurs many times until, mercifully, the movie ends. I can picture Beavis laughing vulgarly from behind the two-way mirror while watching the test group franticly reaching for the remote each time. If you have children and prefer to watch scary movies after they fall asleep, this one is a big mistake. But then it's a big mistake anyway. Here's a thought if you're going to make a horror movie, at least add a gratuitous beheading, a 19-year-old blond girl who screams at the top of her lungs just before she can take off her sweater, the shadow on the wall of someone being eaten alive just out of the camera range, a cat being thrown at the camera to scare the audience, some drifty weirdo with a maniacal laugh, or a monster who looks like a stage hand covered in aluminum foil (a la TV's Lost in Space). These people didn't even try to scare me. They just wanted to hurt my ears. Question: is it a positive review?
