YEah. Can't hear much with the clips. The Silver Surfer theme is nice though, quite soft and sad.
And yes, Ottman has truly exploded his range as a composer as of late. The Usual Suspects and Hide and Seek were mediocre scores with some great moments. Then X2 just evolved his form, giving soem great cues and riffs and pushing in some great themes that would be abandond by Powell, though Powell did a good job in X3.
But Superman Returns was simply amazing. I don't know what he took or shot up with before writing that score, but that score is amazing. Everything from the new Superman theme, his emotional theme, the plane sequence music, to the new "Reprise" take on the Love Story...was amazing. I listen to this soundtrack routinely.
However, I will say that it looks like Story told him to not make it too mature with Fantastic Four 2, as the seriousness of SR is not entirely present. Which is okay, different films with different tones.
