The problem with TASM (and MOS,for that matter) is trying to squeeze a "light" character into a dark & bleak film.Both Spidey & Supe's strength is the wish fulfilment.The sense of exhilaration of being them for an hour,and then having to go back to your day job.Both films completely sacrificed that angle in a misguided attempt to have us "feel their pain".
Now,I'm not saying that neither character has had their struggles,dark moments,blah,blah,blah-but if you start with that "grim" tone,you lose much of the core character.
