Example Input: So it was long, and it was a slow read, big DEAL. Ms Lackey and cohorts have spun a gripping, involved tale of GREAT characters, involved PLOTTING and lots of FUN. I read for pleasure and this was a pleasure. I was always looking back to keep things straight, but it was FUN. I lost most of two nights sleep because I couldn't put it down. This team should write lots of sequels, and I WILL BUY THEM ALL.Be warned, if you pick up this book and start reading you will suffer. Yours friends and family will think you have run away, and you have, To Venice, where you can spend a ripping vacation in you mind. The lady has won me back.
Example Output: Positive

Example Input: Wow..thats basically all i can say. I bought the cd, then realized that they were playin live like 20 minutes from my house. They put on an amazing show! They closed it with do you call my name, then went backstage. The crowd started chanting, "ONE MORE SONG!!" The drummer came out and started playing again. Then all the rest came back out and played one last song. Ra is underrated and a great bunch of guys. I got my cd autographed by all 4 and i got a picture with them. Buy From One, Duality, and SEE THEM LIVE!! My ears are still ringing.
Example Output: Positive

Example Input: I had the misfortune to read the other three books of the series before reading clan of the cave bear but that did not detract from the joy of reading this book.Ayla's story is just that,although the author has written about our ancestors one should not take it as a trueism.Ayla's constant fight for survival and her success inspite of Broud's dislike for her,simply because she is diffrent from him helps push the story along.Their battle of their will continues even after her brutily beats and rapes her.Her decision to leave the clan inserch of her own is out of selfpreservation,leaving her son is hard but so necessary.The book is highly intresting and this authors eye for detail is truly awsom.Keep on Mz Auel.There is a rumor that there is another book in the works.Hurry PLEASE.
