Example Input: I don't actually own this album, but I did buy Apple Venus, and I'll say this: I hope that this album has the charm that that album lacked. I've never been so disappointed with an XTC album. Why would one buy an album of the exact same songs, except in demo form? A shoddy attempt to extract money, it seems. Shame on you, XTC!
Example Output: Negative

Example Input: This book is so unrealistic that it spoils all the fun, super killers like Temple Gault (a clone for the Satan Incarnate known as Hannibal Lecter) are more silly than super. I found all the other character two dimensional and all the "intrigue" regarding super computers insulting to my intelligence. Has Cornwell done better? I don't know and, after reading this, am in no big hurry to find out.
Example Output: Negative

Example Input: My (indoor) cat contracted fleas about a month ago and I used the Zodiac spray on the carpet, upholstery, curtains, and mattresses as I went about treating the apartment. I also used the Zodiac sponge bath (2 treatments/bottle, used both) and one course of the Frontline topical medicine. Today I was brushing my cat and found more fleas. My vet informed me that they have heard nothing but complaints from pet owners who've used the Zodiac products.The label claims that: "One treatment gives continuous protection against pre-adult fleas for 7 months." I used the spray generously but here I am 1 month later right back where I started.Just treating my 2-bedroom apartment for fleas is a costly and tedious task. If you're going to go through this, make sure you use the BEST products available. Talk to your vet and explore ALL your options. GOOD LUCK!
