Bests & Worsts Reviews from Amazon

I am 74-years-old and time is valuable and this book just took a nice chunk of it out of my life. I had never read the works of this author and did like the story outline. Reviews were generally positive, but I place much of that in Stephenson's legion of followers. The technical aspects are far too detailed and excessive. I lost count on the pages dedicated to delta-V. This was symptomatic of the book and especially in the first 500+ pages. I can understand character development, but again - excessive. Will I give the author another chance? Probably - but some folks also remarry an ex.
