On that note, the first sound we actually hear (other than music) is Kal El's heartbeat.  I've got it playing on the computer now.  I believe that this is completely intentional. 
  
  MOS is one of those films, if you put it on in the background (for ambient noise while you're working, or whatever) sooner or later you get sucked in.   For me, I start if from the beginning, as soon as the dream-like music starts and I hear that heartbeat, I'm pretty much sucked in.  
  
 I'm totally on the same page with AVEITWITHJAMON, in that this film is 
 a journey, and an epic one at that .
  I like the fact that it isn't an easy journey, it's a struggle   - which I think justifies the more serious tone.  I liked the fact that his very birth is an act of rebellion, and at the same time Krypton is at war with itself.  
  
 In comparison, I loved Iron Man (the first one), but it doesn't grab you on an emotional level like MOS (could be my bias, as I'm much more of a Super-fan !) but while I cared a bit about about Tony Stark, (who up until captivity had been a self-centred *******)  his journey is becoming slightly morally responsible for his actions.  It's nowhere near the arc that Kal-El/Clark goes through, which is about finding out who he really is, and deciding who he's going to be. 
  
 When he walks out with the suit on it was a massive thrill for me, because it was like Superman walking straight off the page of a comic book  - say what you want about Cavill, but boy he looks the part right down to the attitude- anyway, It's an emotional thing.  
  
 Anyway, when Lois says "Welcome to the planet" and he says " Glad to be here Lois." you feel like he's finally arrived, in terms of deciding who he's going to be.  The journey isn't complete, but he's certainly on his way. 
  
 Definitely gets better every time I see it.  (especially the battle of Smallville, but that's something for another thread).
  
 Peace out Super-fans !  
 
  
 (btw, MOS is so awesome on every level, and made even more-so because it includes one of my favourite Chris Cornell songs, from way back in the early 90's,  "Seasons")
