Example Input: Could have been a great movie . I waited in angst to see this movie when it came out on HBO. I love the Rat Pack and couldn't wait to hear the music. I thought the cast was excellent. The problem was the music for Sinatra, wasn't Sinatra singing.     The result obviously for a fan is pure dissapointment to say the least. Maybe people who don't realize this will like the film and rate it 5 stars. Like I said... could have been a great movie, it just wasn't.     You can't blame the actors. Who are great! Who wouldn't want to have played these parts
Example Output: NEG

Example Input: A Good Introduction To Stability Ball . Swiss ball basics is a 50 minute workout , there is only 10 exercises which are performed in 2 sets of about 10 reps , the instructor shows more advanced variations on the second set and does some stretches in between the sets. Though the exercises can be challenging , the workout is pretty slow paced and let you to concentrate in the exercises. The quality of this video is very good and it is filmed on a sanded area , the instruction is very good also and during the exercises there's some animated pointers.  I think if youre in a good shape you'd be better off just buying his "swiss ball abs" it has most of the exercises from swiss ball basics but it has 3x20 minute workouts in different levels (but there all pretty tough).
Example Output: POS

Example Input: worthless trash . This is a complete waste of time. There is virtually no plot, the whole point of the movie is the celebrity cameos

NEG
