Query: Not much fun

Should have been titled "A lot of Science, A little of Superman". Author spends about 80% of book going into way too much depth about all sorts of sciences and then ties it into Superman's abilities at the end of each chapter. After a while you find yourself skipping the science sections just to get to the Superman parts. Author also states throughout book that Superman came to earth before he was actually born-as a birthing matrix-to support his theory about Superman's adaptability to earth conditions. Is this a recent comic book change to his origin? For those of us who read the comics through the 60's-80's, and have seen all the Movies and TV shows of the last 50 years, Superman always came to Earth as a small child. This bit of revisionism is quite jarring-especially for the older reader who is more likely to pick up this book. Book should have been more fun, save your money.
