Example Input: Review: MINOR SPOILERS!Well i just sat up late and watched this film, mainly because i enjoyed and rated some of Singleton's earlier work like "Boyz n the hood". However, i have to say this was a major disappointment and is everything i hate about contrived, clichéd, so-called "message" movies. The acting is mainly poor,(pop stars and models do NOT necessarily make good actors...take note), the situations hard to swallow, (rape victim becomes overnight lesbian?...please!), but worst of all it reinforces every screwed up stereotype you can think of. By the second half of the film it has become cartoon like in its characterisation, making you lose any shred of empathy you may have had for its one-dimensional players.Not once is any valid point made about the inherent causes of racism and cultural, sexual and political ignorance. As a result it merely ends up sensationalising the results of these problems. It's message is contradictory, resulting in a sense of confusion and a general lack of plot cohesion. As for the films conclusion i found it predictable, embarrassing, exploitative and mildly offensive. For a film called "Higher Learning" i have to say all i learned is to avoid seeing this ever again.If you want a true comment on some of the themes that this film completely fails to elaborate upon then go hire "American History X"....unless you were just watching it for Tyra Banks then go hire a life. Question: is it a negative review?
Example Output: yes

Example Input: Review: Steve Carell once again stars in a light romantic movie about choices, family and pressure. By judging on the plot and cover art of the movie I was expecting a flat-out comedy, lots of laughs and unrealistic elements, but I guess I was wrong. Sure the movie had some comedy, but it felt much more of a light Drama to me and Steve Carell once again gave a great performance. The movie itself really tackles true observations and that was a strong element I found. But, the ending felt a little bit rushed and predictable. Through-out, the cinematography was great, the acting was great and the message it delivered was obvious but yet still very important. Though, it came down to old, flat and predictable ending. I'd reckon if different choices were made at the end of the movie (perhaps for the bad, even) this movie would get better publicity. Still a fun movie. Question: is it a positive review?
Example Output: yes

Example Input: Review: As a grownup in my mid-40s, I am not even close to any of "Nancy Drew"'s key demographics, but I was pleasantly surprised by the film this afternoon; so, I could tell, were the pair of sixtyish silver-haired ladies down the row from me. The older man who left the theater just ahead of me specifically praised the film to the 20-ish female usher (who said she'd seen the film the previous evening and quite liked it).More to the point, however: In the row just ahead of me, there were nine -- count them, nine -- ten-year-old girls lined up next to each other, passing popcorn and hot dogs and candy back and forth and giggling through the previews.Once the film began, they promptly settled down to watch........and didn't so much as peep till the closing credits began to roll.This is not a perfect film; it doesn't quite pay off its high school subplots, it's not quite confident enough of its own tone, and its thugs are just a hair too far over toward critically inept at times. But the adaptation of the source material is essentially respectful, the plot hangs together fairly well, and it treads deftly between the sins of excessive cheesiness and excessive modernization. Last but not least, Emma Roberts carries the movie with startling grace -- Josh Flitter's superb timing notwithstanding, this is Roberts' movie, and she pulls it off beautifully. Her Nancy Drew is very much the direct ancestor of Kristen Bell's Veronica Mars, and the film is also a lineal descendant of Jodie Foster's early and underrated "Candleshoe".In today's marketplace, it's a rarity: a family movie that respects its viewers' intelligence. As such, it won't be to everyone's taste -- but for what it is, it is the best movie of its kind in decades. Question: is it a negative review?
