Query: Most boring book I've read in years

I just can't understand how this book could get such good reviews. Comparisons with The Name of Rose are outrageous for a great author such Umberto Eco is. The Da Vinci Code keeps you stuck to the book, the Rule of Four bores you to death with details about college life that are neither relevant to the story nor interesting to anyone who has not been at Princeton. The two young authors have way to go to raise interest in the European public (I invite you to look at the UK reviews). Is there perhaps a riddle in the book that unveil the true story I haven't found and other reviewers here have?
