Yeah I think I'd be happy with that too.
So let's say Zod is somehow responsible for an explosion or derailment of a subway train. People are hurt, terrified, with no idea what to do. Some people are trapped under debris. Fire is spreading, the smoke is thick and people start clambering over each other to get to an exit.
And through the smoke comes Superman, dressed in similar clothing to the man who did this too them.
At first they panic more. He has to ignore it, focused on getting everyone to safety. His first action is to free a man who is trapped under some debris. Everyone shuts up, as the man clambers out from under it, stuttering a thankyou. He then puts out the flames with his superbreath, before looking back to the people who are now just staring silently at him.
He pauses with a slight moment of doubt and hesitation (the 'I hope this disguise thing works), and then confidently says 'This way', his voice authoritative and unquestionable.
Cut to people emerging from the at the nearest platform, running towards the emergency services people who are on their way into the devestation. One of them asks 'what happened in there?'
Then maybe cut back to Lois, who is unconscious, slight cut to her head. She starts to come too. Blurry POV shot of a battered carriage, filling with smoke. She starts to cough, tries to get to her feet, but wobbles and grabs onto one of the seats. POV shot again as we see a blue and red figure of a man coming through the smoke towards her. He catches her as she starts to faint.
Flashes as she goes in and out of consciousness, of her POV of Superman's chest as he carries her out and places her on a gurney where paramedics start fussing over her. She's confused, trying to sit up slightly. One last POV shot of Superman's face, blurring in and out as says softly (but manly

) 'Your safe now' before backing away. As soon as he's out of sight, fade to black.
I think it'd create a good split of public opinion too. Most people focusing on how the tragic subway incident was caused by the kryptonians, but Lois and some others running stories on the one who helped them. The Emergency services, all the people who escaped because of him, would all be eager to tell their story.
'He's not like the others. He helped us.'
I know some people would prefer some big CGI infused scene of mass destruction, with Superman's flight being key.
But personally I'd say something like that belongs to the final battle, and makes it even more exciting.
I wanna be able to see what being saved by Superman would really feel like. If you were on your own, trapped, scared, in pain and sure you were a gonner, and then this man just came in and took all that fear and danger away.
I just really want them to emphasize what Superman represents - hope, at the point where normally there would be none.
