No struggles of her own.
Except the whole
"My father was impaled by the lizard's claws" thing.
Really, I'd love to hear some Love interests in superhero movies who had legitmate problems that in some way weren't related to the superhero. ie (MJ is sad in SM2 because Peter didn't show up to her performance, Rachael is sad in the Dark Knight because she's dead)
I think the "strength and independance" thing comes from, just off the top of my head;
- Her saving Peter a couple of times
- Havings interests outside of Peter (Job, Friends, School, Scholarships)
- Actively being involved in aiding Spider-Man, not acting as a damsel in distress every single fight. (Lizard in Oscorp, Electro in Power Plant.) Also, I get that Harry in the end made her a damsel in distress, but even then, there was none of that incessant screaming stuff, the heeeeelp me stuff, that you get from other love interests.
- Working independently of Peter. (Finding out who Max Dillion was)
- Not taking Peter's constant ***
I think its disengenious to say, "other than her relationship with Peter and the actress who played her, the character was bad".
The fact of the matter is that the relationship is a major factor for the love interest. Unless you want another spin-off movie, you were only going to get snippets of Gwen's life. You can always go the SM1-3 way and have the love interest get with every major male character in the series and sing in broadway to prove their independance, or go the Thor 1-2 way and be like, "oh she's a scientist, she's pretty AND she's got "extremis ex machina" flowing through her!"
The chemistry between the two leads (in terms of romance) is paramount. This is what set Gwen in the TASM series apart from other similar love interests, is that the chemistry was real, and what followed from that was an actual push to
care about the relationship itself. The directors sometimes said the Stone and Garfield, "Just go for it". That in of itself is good directing, to be able to put the actors/tresses in positions that facilitate their best performances.
Its like saying, "other than the wheels, engine, set, ect. of the car, the car drove poorly."
