Ex Input:
I wouldn't recommend this book to an enemy. True, the information may be worthy, but the writing style and the narration were horrible. It is definitely NOT written (nor read) in a conversational manner. I'm willing to cut the narrator some slack as he was only reading what was written, however better inflection, phrasing, pauses, etc... would have greatly helped this otherwise tedious book.I couldn't even finish it. I suffered through the first 5 disks and after all that investment in time I couldn't bring myself to listen to the 6th. Its just that poorly written.I'll restate the fact that the message -- the information -- is worth hearing, its simply written in such a tedious manner that I couldn't stand to hear it through the end.I think I'll donate it to my local library.

Ex Output:
Negative

I bought this air mattress to use while my new bed was being shipped from back east, the bed lost air every night and I woke up almost on the floor. I tried to send it back but it was impossible to get back into the box.

Ex Output:
Negative


Ex Input:
Amazingly silly dance routines. Baaaad acting. Lame, lame, lame story (I particularly love how the meteorite happens to land right next Peter and Mary Jane while making-out on a giant self-made web). And all for a mere $60 retail. Thank god for Amazon! If you're into this sort of thing that is. Don't let the effects dazzel your brain, this is truely one of the worst comic book movies, yet. And it's Spiderman, how can you screw that up.

Ex Output:

Negative
