You know, there's a very good reason Roger Ebert won a Pulitzer. The man is an amazing writer. If you enjoy the pure pleasure of reading, and have a passion for the movies, you would be hard-pressed to find a better book than this to read.
The book is mostly a collection of writings by Ebert over the last several decades. There's some interviews with famous film folk, a collection of essays on subjects such as colorization, digital vs film, the need for a viable "adults only" rating, a few movie reviews, a discussion on the past, present and future of film review, and, most importantly, a serious love of the movies that comes through on every page.
Now thanks largely to Roger Ebert I've began to really develop a love and passion for movies in ways I never thought that I would. Just looking over my recent purchases on Amazon, I see things like Babette's Feast,Russian Ark: The Masterworks Edition,All About Eve, All Quiet on the Western Front (Universal Cinema Classics), the "Godfather" films, and many others. Roger Ebert really opened my eyes to the glory of film, and helped me to understand why something like "Sunrise", is a glorious movie and something like "White Chicks" is not (hint: the abscence of anyone named Wayans helps).
I cannot recommend this book enough. If you like movies, buy it. If you like reading good writing, buy it. If you even think you might like this book, buy it! You'll be doing yourself a favor.
