I'm honestly pretty surprised that a lot of people here don't like the current game. I wonder how much of it is judging "good" (or fun, enjoyable, whatever) by what you "grew up" (in a basketball fandom sense) watching. If you came of basketball fandom age when the game was a grind-it-out affair with centers on the low block ruling the game, perhaps it's hard to see anything else as a legitimately positive way to play.
I think the quality of the game has never been higher and the ball-movement, hunt-the-best-shot style that the Spurs and now the Warriors exemplify is fantastic--it's similar to what the Lakers and Celtics in the 1980s embodied, except now the three-point threat has "widened/lengthened" the playing field.
I think the defense is also much more sophisticated than it's ever been. It's easy to think that defense is no longer played due to the amount of scoring happening and the up-and-down pace but, really, defenses are just in a much tougher situation due to both the movement/passing based offenses and the fact that the floor is spaced so much more than it was in the '80s or '90s. I think watching an athletic switch-heavy defense that plays together really well, like the Warriors, is extremely enjoyable.
