Just listening to his KINGDOM OF THE CRYSTAL SKULL soundtrack. I get the same feeling I had listening to Jerry Goldsmith's score for STAR TREK: NEMESIS. Both score for the most part are effective and in many ways beat 90% of what so called film composers call music, and yet Williams and Goldsmith clearly show (or showed in the latter's case *tear drop*) that their best years are far behind them. Still a good listen, but sad to know that spark he had during the last quarter of the 20th century is no longer there.
Eh, I'd give his scores for TINTIN and especially WAR HORSE a listen before I write him off completely. He's still got gas in the tank; I think it's more (in both cases) them taking a score because it was expected of them, not because they felt particularly energized by the material.
