My Kids Love It . My 2 & 3 year old love this movie. They love to dance to the music. Garfield is so entertaining. This was a great buy.
Answer: POS
Explanation: The overall sentiment of the review is positive as the reviewer refers to the dvd with positive expressions such as 'love it', 'entertaining', 'great' etc. Hence, the label is 'POS'.
Part 3. Exercise
"Always Be Closing!" . Glengarry Glen Ross is a superb drama directed by James Foley (At Close Range), and starring a powerful all-male cast including Al Pacino (Heat), Jack Lemmon (Grumpy Old Men), Ed Harris (A Beautiful Mind), Alan Arkin (Edward Scissorhands), Kevin Spacey (American Beauty), Alec Baldwin (The Aviator), and Jonathon Pryce (Pirates of the Caribbean: The Curse of the Black Pearl). The movie is an adaptation of the stage play written by David Mamet, who also helms the screenplay to the movie version. The thing that drew me most to Glengarry Glen Ross was the dialogue. And since I tried my hand at door-to-door sales, I felt very connected to the characters in the movie, especially Sheldon Levene, played remarkably by Lemmon. The presentation made by Alec Baldwin in the beginning of the film about what it takes to be a salesman hit me harder than an iron fist. The movie is not just for salesmen (even though I find it mandatory for anybody who's considering a career in sales), but for everybody who appreciates real movies. Recommended

POS
