What can I say MovieBob? You're just wrong on almost all of these things (except Zod, fucking brilliant). Also, they're not really 'falling for one another'. They're caught up in the emotions brought about by their circumstances, and what's better, they know it, that's why the film makers didn't simply have their first two almost-kisses immediately interrupted by events, Lois and Clark awkwardly delayed it themselves because they both knew they were mostly just caught up in events but also knew they needed and wanted an outlet. It's even more brilliant cause the film makers must surely have been aware that the audience expected it and that the audience would be pretty pissed at the cliche at the same time. If they were really 'falling in love', they would have kept in touch before he just showed up at the Daily Planet. She was not expecting to see him. So, what emotions? Well, it might be cliche, but it's really true that people usually like you more if you save their lives. That handles Lois. What of Clark, he knows he's unlikely to die, so what's he feeling? He's an outsider on an alien world, and he found someone to trust.
Yes, the movie is taking itself somewhat seriously, but they're just defining Superman for you, that's all really. Go take a look at the DeathBattle episode of Goku vs Superman. Clark knows he's different, this causes angst in sentient beings, don't know what else to tell you; other than they didn't lay it on too thick so I'm cool with it.
Only complaint is the city destruction fight actually did go on too long, which is not something I thought I'd hear myself say ever. Of course I was in slight physical discomfort from the theater's speaker system at the time.
