The characters in this book are so incredibly dumb. They say idiotic things, like when the girl is trying to get into the library she's on her phone and someone comes out of their room knocking at the house who they think it is, then proceeds to tell her not to. Just dumb stuff. I couldn't finish reading this...
Bad review

I was quite pleased over a product that is easy to use and produces good results. The price was also great. It will become my regular hair cutting product. Thanks Amazon for making it easy, safe and economical.
Good Review

The book would be an OK value at twice the price. There might have been some really interesting research undertaken in trying to establish a list of the top 100 movies ever made and their critical success or failure, however, this kind of writing about movie review is very dry. It lacks focus throughout and could certainly use tighter editing. While I suppose if you are writing historical analysis, it makes sense, but for most readers, there were parts here that seemed so unfocused as they ran on.

Bad review
