Anyone noticed how the characters in the Alien movies (the ones about Rippley) got progressively dumber as new chapters were released?
Don't remember it? Try to watch them in a row, it's astonishing. It's a good "exercise" because them being part of the same series makes it much easier to make comparisons.
I'd say that's what makes a big difference between the first one and the rest, not the plot in itself, but how idiotic are the characters after the first chapter.
"Bertrand Meyer is, hands down, the best writer in the computer field, because of a simple reason: his books have both great content and great prose. Not all authors of computer books (and certainly not the one you are reading now) can make the same claim."
