I am anxiously awaiting the arrival of my CD. I was at the concert in Atlanta and was mesmerized during the entire show. It was so surreal..to be in the company of Barbra and Il Divo. I know the CD will be great. It will be the first thing loaded in my car. And, it will probably stay in there for quite a while. There is and will be no other Barbra. I only wish she would tour more often.

Ex Output:
Positive


Ex Input:
There's not much learning either. Sheri is incredibly condescending when she mimicks pregnant women. This video could also really use some visual aids besides Sheri holding up a poor illustration, writing lists (that she doesn't finish) on a whiteboard and the worst...her on the ground, legs spread in high-waisted khakis demonstrating childbirth.

Ex Output:
Negative


Ex Input:
If you like Slayer then this is a must album. The drums with Dave Lombardo are once again simply perfect. The songs are very rhytmic and aggressive. The sound of the guitars and the vocals are really great. Just buy this album .

Ex Output:

Positive
