Ex Input:
An exellent study of the German Airforce from the fall of Sevastopol in the Crimea to its failure at Stalingrad. Very well written, with a clear analysis of the events. Well worth the money and it belongs in every major collection on World War II's Eastern Front.

Ex Output:
Positive


Ex Input:
It's not at all what I expected. Still have not found what I was looking for in thefirst place

Ex Output:
Negative


Ex Input:
To me this was the beginning of the end for the Wilson sisters. Sure, there are some okay songs on here, or so I thought until I recently replaced my vinyl LP with the CD. These songs sound so dated that I can't believe I used to like them. To put it mildly, this album was Heart's contribution to the 1980s "hair band" movement. Synthesizers and drum machines have taken over for Nancy and Howard's guitar playing. Dreamboat Anne and Little Queen still sound as good today as they did when they were released. This CD does not.

Ex Output:

Negative
