Dude,
first, I have greatly enjoyed this conversation. I'm not even an amateur when it comes to music, but I recognize the amazing impact that a great score has on a film audience, myself especially.
So,
on a related note, perhaps you are disappointed, because you have pitched your expectations too high. If you use Williams' original Superman score as
a comparator, then it would be hard not to be let down by anything that
was less than stellar -and something that nobody seems to be able to do today, which is to create instantly recognizable scores and motifs
for film characters.
Having said that, HZ is still pretty damn good (again, I refer to the Joker's motif from TDK, Batman's motif -and the often overlooked Harvey Dent motif- pretty good I'd say).
Personally, I loved what he did with MOS. I felt that the Clark Kent motif was used just enough, in the right places, and that really helped set the mood for those particular parts of the film (e.g. "You're the answer son" ). If anything he erred in bashing Zod's theme a bit too hard, and not giving us enough of the new de facto Superman theme (the end title, teased in the "flight" scene).
Okay, that's old ground, here's my real question. How does HZ's MOS work compare to Silvestri's work in Avengers , or for that matter anyone else doing work in the superhero genre? To my mind, Avengers' score was utterly forgettable, the end title (the Avengers' theme) was only mildly memorable because it was so damn repetitive. Ugh !
I would argue that Marvel has utterly failed to create a memorable theme or motif for any of its marquee characters, because it chops and changes composers so often.
Thor deserves a mighty theme, as does the Hulk but neither has got one.
I remember the music in Iron Man being nicely suited to the action, but not staying with me afterwards....other than the AC/DC (now THAT was a nice touch).
(as I type this I'm listening to the Kung fu panda score, where HZ creates solid motifs for the characters, particularly for the lead, and also pays tribute to some musical conventions used in old style Kung fu films).
By comparison, at least both Batman and Superman have themes that we can recognize when we hear them.
So maybe HZ wasn't quite on Williams' level, but boy he's about as close as current composers get.
Maybe, Howard Shore's in the same class as HZ (I'm basing that on his amazing work in Lord of the Rings, talk about motifs and character, wow !).
Perhaps, listened to with that in mind, HZ's score still may not reach your expectations, but you may discover it's at least strong and distinctive enough to stand out head and shoulders above other super-hero films.
(BTW I concede HZ isn't perfect while I loved TDK's score, I found TDKR too bombastic, it actually over-shadowed the action and pacing, rather than accentuating it. Not great).
Also, MOS shows its musical class, because it has a classic Chris Cornell song,
"Seasons" from way back in 1991. I'm a big Chris Cornell fan, one of the most distinctive male voices in popular/rock music of this generation.
cheers.
