Query: Disappointing

I ordered this book after the good reviews here. Unfortunately I am deeply disappointed. The material in this book qualifies only for a good short story. The author has stretched this good essence with repetitions and dumb dialog. It is like those cheap Sci-Fi channel TV series such as Eureka and Stargate Atlantis.The dialogs are setup to lead to "Sci-Fi" ideas, but in such an obvious and lengthy way that finally when it comes you have already lost your interest.Sadly this seems to be the trend in most of the recent Sci-Fi books I read. If you have read one of the great classics such as Arthur C. Clarke's Rama, you would know what I mean.
