Example Input: "Subrosa Subway" hooked me right in. "Calling Occupants" a masterpiece. No one thought it could be done...the Beatles sound in an experimental way, but my goodness, an attention and care to arranging was astounding. No mop top hype to hide behind.The fact that they wanted it released with no individual song credits made it feel like a group effort. As they wanted no one to look at the album in none other way than an experience. And they the achieved with flying colours. This album is the reason I even got into songwriting or noticed songwriting as an art form.Indeed a special album for me all time.
Example Output: Positive

Example Input: Sold as red, obviously.But I find them to be more pink than dark red. I'm sure they're still legal (or hope they are), but not the look I was hoping for / expecting.Otherwise, they work fine.
Example Output: Negative

Example Input: This was the first Patricia Cornwell book I have read. She is a compelling storyteller, and she obviously possesses great knowledge of the subject matter. I do admit to finishing the book in a two-day period, but it was more to get to the inevitable final showdown between Scarpetta and the killer. Scarpetta and some of her cronies are characterized well, but the killer seemed a bit stereotypical. I don't believe in reading ahead and spoiling the surprise, but in this case I skipped some detailed sections to find out how the killer would be stopped in his tracks.Since reading this book, I have read Cause of Death by Cornwell and would rate that book slightly higher than this one. This book is not her best that I've read so far, but it wouldn't prevent me from reading another one.This is a good, focused, and knowledgable writer who does not need to fall back on unbelievable killers and sensantional plot devices to tell an imaginative story.
Example Output:
Negative
