This book was a huge disappointment. I felt that the writing style seemed forced and unrealistic. It is written more like a blog than an actual book. There are tons of grammatical errors in there (typos, missing punctuation, etc.). It's almost just a collection of random thoughts without any attempt at order. The best part about this "memoir," to me, was reading some of my favorite pop culture references. Don't buy this. Not worth it. Even free it wouldn't be good.
Output:
Bad review
