Example Input: Review: This movie is S-L-O-W. Spent most of the movie actually waiting for it to 'begin'.The setting was bleak, the script was bleak, the cinematography was bleak, the plot was bleak, the budget was low (not that all low budget movies are bad, but this one had no redeeming features).The plot was more consumed with a vengeful, slightly deranged hunter than the actual Wendigo which made a very brief appearance toward the end of the movie. This in itself was disappointing as this 'Wendigo' was just a bizarre mix of a tree and a stag. Everything about the movie was uninspiring.The parents of the little boy appeared to be rather aloof and at times seemed completely detached from their son. Whether this was down to bad acting or a bad script I'm not sure, but it only heightened my disappointment and boredom levels.There was no food for thought, nothing to pique an interest. With no real intrigue or chill factor, this movie creaked along so painfully, you just couldn't care less what happened by the end.Wendigo's ambiance reminds me of the dull movie shown at the awards ceremony toward the end of 'Mr Bean's Holiday': a movie which is artistic and nonsensical, trying too hard to to be deep and meaningful, but coming across as pretentious and boring.I would never want to watch this again. I only watched it to the end in the vain hope that something interesting might happen ... but it didn't. Question: is it a positive review?
Example Output: no

Example Input: Review: I read the reviews before i watched this movie, and i didn't believe them. I love crap movies and i expected this one to be average. It wasn't. This film makes Camp Blood 1 and 2 look like greats. The film contains bad acting, poor sound, poor confusing storyline, bad makeup- and it bored me so much i turned it off. even the nudity was rubbish! Did they even have a budget for this film? I don't think they did. You can tell if your gonna like this film or not in the first 5 minutes. if u want a good cheesy gory film go watch toxic avenger 4 or even camp blood. Avoid this trash - I watched it on TV and felt riped off, so don't spend anything on it. The best part is probably the end. Question: is it a negative review?
Example Output: yes

Example Input: Review: Although I use this site quite frequently to see how other people rated what I think are challenging or just plain enjoyable films, after watching this "movie" on Film Four last night I felt compelled to write something down, even if it just helps cleanse me once again.The film was possibly the shallowest experience I've ever had - the main characters played by Danny Dyer (23? You sure?) and Gillian Anderson (who will always be Scully as Leonard Nimoy will always be Spock) had no real substance about them - I'm not sure if the first half-hour of the film didn't make the final cut but surely in a revenge movie you would like some empathy with the victims... here I couldn't care less. In fact, the only character I did seem to care about was the dog, with the stag coming a close second. And both animals out-acted Dire (sic) and Scully, who were quite frankly terrible. I guess though you're only as good as the script you are given, and I'd like to warmly thank the writers, the producers, the director and all of the cast for wasting 90 minutes of my life and some perfectly good electricity.
