Example Input: where to bloody begin.... ah.. in my junior year i and everyone else in class was forced to read the book and watch the horrible origanal slow and boring movie. after we got done with it almost everyone in the whole dang room yelled out that it suck, right at the same time. both this and the great gatsby sucked. but i dd surprisngly enjoyed the great gatsby movie towards the end of it
Example Output: Negative

Example Input: I haven't been able to watch this much because the DVD won't play in my normal (otherwise functioning) DVD player. It will play on my computer's DVD player, but without sound. The DVD will play fine on my laptop, but that's not a screen that's very conducive to practicing in front of. The DVD does play on my friend's DVD player for some reason. Also, I bought volumes 1 and 2 and both are so short, it seems obvious that they could have put all of the lessons on one DVD. I guess they knew they could make more money by making us buy both.
Example Output: Negative

Example Input: Much more durable than the Apple adapter (my Apple one broke in 2 months), and MUCH better priced. I think this is the best one around for the value. Only downside is that there is no indicator as to when it is charging (the Apple one has Green v. Amber color). All in all, a great buy.
Example Output:
Positive
