Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Timeless classic, awful quality eBook

The book itself will always be timeless and I think it would be daft to write any kind of review on a book so well-known and loved.So, instead, I wish to berate the awful quality of the bonus material at the end of the book that is largely illegible. Considering the price of the eBook and the unfortunate quality of the bonus material, it's hard not to feel ripped off.Hopefully Amazon will deal with it and upload an improved version at a later date.For now, apart from the convenience of having it in digital format, it's not worth it.
