TASK DEFINITION: In this task, you are given sentences from movie reviews. The task is to classify a sentence as "POS" if the sentiment of the sentence is positive or as "NEG" if the sentiment of the sentence is negative
PROBLEM: A bracing , unblinking work that serves as a painful elegy and sobering cautionary tale .

SOLUTION: POS

PROBLEM: A chilly , remote , emotionally distant piece ... so dull that its tagline should be : ' In space , no one can hear you snore . '

SOLUTION: NEG

PROBLEM: For all its shoot-outs , fistfights , and car chases , this movie is a phlegmatic bore , so tedious it makes the silly spy vs. spy film The Sum of All Fears , starring Ben Affleck , seem downright Hitchcockian .

SOLUTION:
NEG
