Example Input: Taking guitar lessons to a new level . This is a great DVD.  The guitar style spectrum is covered here with country, blues, and rock, with tips and tricks to enhance your own style.  Greg uses Fender Strats and Telecasters (my favorite guitars) throughout the video and explains and demonstrates his unique style in a way that you can pick up on with a little practice and not be totally discouraged.  This DVD is filled with humor, great teaching and superb pointers for expanding your technique.  If you are a fan of Greg Koch or would want to make your playing really stand out, you need this video
Example Output: POS

Example Input: No Stars from a  Cold War Submariner . I watched the film in the theater when it came out, was very disappointed in all the inaccuracies. Trying to "entertain"/ educate people on a subject matter so serious with a plot so ludicrous is irresponsible at best. The Pet Dog was cute but also unrealistic. The book "The Gold Crew" had a more believable plot.      Having served on a few Ballistic Missile Submarines, I find it an insult to the Crews of the Boats Especially to the Captains and officers.     It's Understandable why the Navy Refused to Bless this. By placing there seal of approval on this film they would be saying it could happen, which it couldn't as depicted. Too much control and too many people in the loop to allow it.     From November 15, 1960-May 25, 2001. The Navy completed 3500 Deterrent Patrols which roughly equates to 671 years of combined ship service on alert ready to launch. And there Still out there boring holes in the water
Example Output: NEG

Example Input: Not heavenly but definetly a dog !!! . Joe Camp should hang his head in shame for making this piece of trash. I assumed it would be good because he has made good clean family films before. This ain't one of them. This film has indecency in it and is not fit for family viewing. Don't waste your time or money
Example Output:
NEG
