I have read the five star reviews, and sadly, I can't give the same rating.
Prior to the book, I really liked Penny Marshall. After reading the book, I can't say I feel the same.
First, just looking at the book itself, the writing is okay...she talks like she is having a conversation, rather than writing "literature", and I like that. But, her conversations are somewhat superficial. There is no true insight into Ms Marshall. No great revelations of a "gee, that's really amazing" when it comes to her personal career and those celebrity friends she name drops ad nauseum (? spelling).
As far as what I walked away with? I found her lacking in any warmth, except when she talks about Carrie Fisher. She wasn't a good mother. She makes no bones about it, and no apologies or sincere regrets. She didn't like, respect or appreciate her parents. Her mother wasn't a great, loving mother, I got that. Her father was a blah personality, I got that. But honestly, nothing gave me the impression she tried to be a loving daughter, either, other than she moved them to California and helped support them financially, but that was done more, I got the impression, because she had the money to do so and was expected of her. You did drugs....I got that. Over and over, I got that. She apparently didn't care much for her sister, because I didn't see any overtures of closeness or wanting to be close to her...more pointing out her sister's faults.
I am sure that this is Penny in real life. Her words certainly ring true, and I appreciate the honesty. There was some humor, often sad or black humor. No true insight into her marriage with Rob Reiner or other personal relationships...everything seems to be glossed over.
Save your money, borrow from the library, or share with Kindle people by trading. I appreciate what Ms Marshall did in her career, and I appreciate her talent. I don't think I care for her as a person, and that taints now how I feel about watching her or her films she directed.
