I'm in complete agreement with you on this point. For the most part I much prefer offensive sets to a plain iso.
This Truehoop post focuses mostly on crunch time but it details nicely what I see as the pitfalls of too much iso and not enough movement.
Having said all that, when I watch basketball there are times when extreme talent can overcome the restrictions of how basketball should be played. To paraphrase KStat (although he may not have meant it this way), Michael Jordan, and other great players, can "break" basketball. A bad shot by Jordan, or Bird or Kobe, is not a bad shot. It's a great shot because of their talent, as well as the psychological aspect of dominating another player. I always love to listen to interviews with players who have played against Kobe because they sound so defeated. They sound almost resigned to the fact that Kobe will score on them whenever he wants. That psychological aspect can't be quantified but I see it as valuable nonetheless.
