Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: Crap, crap, crap. Bad acting, big explosions, and video game CGI a good movie does not make. Like a 2 hour Hasbro toy commercial. This film made Star Wars Episode 1 with Jar Jar Binks seem like an Academy Award worthy film. And I'm a Superhero/Godzilla/Monster geek...this is just awful...terrible. At least the first one was semi-watchable--and where's Megan Fox? That would have been the only redeeming quality in this junk-fest...I mean alien robots who change into cars and trucks??? It's a movie based on a TOY for God's sake! A bad toy made into an even worse film. Avoid like The Plague.
Example Output: Negative

Example Input: overall, the documentary was pretty cool. however, about 99% of the beach boys clips were from a prior documentary, an american family from '85. they should have included the clip of dennis singing manson's song never learnt not to love (aka cease to exist). especially since the title of the movie is the beach boys & the satan. but did have cool footage of interviews with dick dale and dean torrence and the chantays. also kim fowley was cool too.
Example Output: Positive

Example Input: "Subrosa Subway" hooked me right in. "Calling Occupants" a masterpiece. No one thought it could be done...the Beatles sound in an experimental way, but my goodness, an attention and care to arranging was astounding. No mop top hype to hide behind.The fact that they wanted it released with no individual song credits made it feel like a group effort. As they wanted no one to look at the album in none other way than an experience. And they the achieved with flying colours. This album is the reason I even got into songwriting or noticed songwriting as an art form.Indeed a special album for me all time.
Example Output:
Positive
