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: When I first heard Ra's "From Zero" I was in awe. A band that used cool effects, Egyptian scales, and was moderately heavy--the perfect mix for me. Then, Duality came out.Duality demonstrates a lack of creativity that was once there in Ra. I wouldn't say they evolved, I'd say they devoled. They still use effects, but rarely and they don't have as big of an impact. On top of that they hardly sound Egyption on the album. As for this album, Ra sounds more like other bands, but they are still distinct. I just wish they went in a different direction.I do want to say that their are some really awesome songs like Fallen Angels, Undertaken, and Taken. The other tracks are bad either, it's just that I expected a whole lot more.
Example Output: Negative

Example Input: This printer has been a nightmare. First I can not usemy Visioneer scanner. They say it is not compatable.I removed a jammed paper, and since then anything I print,such as invoices, checks and such, come out with blotchedprinting and paper tears. I get NO help from technicalsupport(They're learning). No 800 number, which means youhave to call CA on your buck.I used to swear by HP. Now I am convinced that theirproducts are close to junk. My opinion is STAY AWAY!
