Query: This book is a maelstrom into soulessness

I have read little by Crichton. But whatever it was, it made me not enjoy his type of Science Fiction. Two of the few things that I did read were "Jurassic Park" and "Sphere". Both, I thought, hopelessly losing their slowly developing content before me. "Sphere", however, was an exception, for it was just a non-exaggeratingly empty roll of toilet paper with unwise words and a constant morphing of a worsening story. The story seemed promising and exalted me even when I looked at the appearingly deep-in-meaning cover. I must say that I was constantly saying to myself: "What a good book this is!" all the way till the four fifths mark. That's where things got so lousy that I even considered quitting on the book, something which I rarely do. To tell the truth, I couldn't believe what pure adulteration of a good initial plot my eyes were witnessing. I finished it, but with much regret and with four days of wasted night-life.
