Example Input: Hi i got this game by trading my brother for some stuff he wanted and i started playing it and was disipointed cause you have to shake it so much. But luckily i figured out how you can get in battles and stuff without having to shake it at all. But it depends on if you you have a massage chair or not because if you have one you can set your magaman pet on it and it shakes it!!! I was so glad when i figured out how to get in battles without shaking it because my arm was hurting now i find the game real fun. I hope this review helped you see yah.
Example Output: Positive

Example Input: This is one of those books that I like the *idea* of, but not so much the execution. It's gotten to the point where if a book has the word "spooky" (or a variation) on the cover, I'm just going to assume it's not. The idea - offering ideas for six themed parties - would make for an excellent book if they were all actually Halloween-themed. Sadly, even the Halloween-specific party suggestions fall a little flat.
Example Output: Negative

Example Input: I've bought several air beds from various manufacturers. I bought one identical to this one 1 1/2 years ago. It was comfortable but lost air after 3 months. I justified this as the user may have not taken care. However, I now believe its the brand. This one would not inflate at all. I will not buy this brand again. I've had great life from a better brands.
