Input: Well this book is a great story, although it was badly written in my opinion. The author used too many commas and he often skipped from one character to the other with no warning. And some of his words were just plain wrong! He told us about Jack telling him they are brothers but at that point I know what it means. So where he jumped into saying these characters were brothers when they weren't it made me wonder if English wasn't his native language or something.
Output:
Bad review
