I stumbled upon a book by James Franco on Amazon.com a long time ago, and it had a 4-star review on the search page and on the product page. I thought this was bizarre, because I just happened to have read reviews of it on literary and nonliterary sites giving it extremely poor reviews. I clicked on "See all # customer reviews" on the Amazon page and the average rating on top immediately went down to 2 stars. I thought this was a glitch, so I tried to access the product/book page a different way. The same thing happened to all of them. There were always the same amount of reviews, as well. About 6 months later I looked up the book again, and the "mistake" was gone. But I had taken a screenshot of it the first time, and there was only two more reviews. The 4-star average appeared on every page. I look for it now, and it is back at 2 stars like it always was. The book in question is Actors Anonymous.
