I am a very strong admirer of Epstein's "The Big Picture," and found his "The Hollywood Economist" strong -- but mostly because it contained most of what he'd already written in "The Big Picture." What I found weak in "The Hollywood Economist 2.0" is the lack of thoughtfulness. Epstein loads 2.0 with several pieces he's written for other publications (or his blog). Unfortunately, these often lack consistent tone of voice with his book chapters, making for an uneven reading experience. There is also a great deal of repetition in the added material, which means you get less for your money (and investment of reading time) than you might think.
Some of what Epstein has included in 2.0 is outright dated, even wrong: His discussion of Netflix is highly outdated (Netflx is stronger now than ever before due to VOD); his analysis of why HBO likes adult fare is terribly dated (in 2013, Epstein writes that HBO is devouring Hollywood's teen-oriented product voraciously); and he still doesn't really address the economics of 3D, or where that technology, pricing structure, and studio commitment is headed. But some of what he includes provides information that you just can't find elsewhere. His reporting on Hollywood is excellent, heads and shoulders above what you find in the "New York Times" or "Los Angeles Times" or "Associated Press" or, even, "Variety" or "The Hollywood Reporter". Epstein is not embedded with Hollywood, and it shows in his strong reporting.
One final note: This book STILL STILL STILL lacks an index! What the...??
With the dated information and repetitiveness, "The Hollywood Economist 2.0" should be required reading only if you've not read "The Hollyood Economist" or "The Big Picture". If you have read his earlier works, you'd be better off just reading his blog and not buying this. Wait for a real, honest-to-goodness revised-and-updated edition.
