It is when compared to the other movies.
None of them were brave enough to actually kill off a major protagonist. Amazing killed off both Gwen and her Dad.
On the other hand, Rachel Dawes.
Raimi's killed off a few bad guys... and the rest of the MCU have threatened to kill off good guys, but there's always been a miraculous reversal of the situation.
Pepper Potts in Iron Man 3 had a miraculous cure for her DNA being messed with, for instance... or Bucky Barnes being resurrected... Loki, a kind of anti-hero, died then came back.
Nick Fury? Faked his death... ta-daa! Everything's fine after all!!
I'll have to concede Pepper for now because I don't remember
IM3 all that well. When you say Bucky, do you mean when he's brought back as the Winter Soldier, a brainwashed abomination whose return ends up causing massive problems for the heroes instead of being a simple "everything will be OK" development? Also, Loki (who never actually becomes any kind of anti-hero, merely a villain that is forced to help Thor out in
Dark World) is a duplicitous trickster who specialises in playing long cons so him faking his death (and disguising himself as Odin) as part of a greater scheme makes more sense. The same arguably applies to Nick Fury, whose faked death makes sense when S.H.I.E.L.D. is compromised and he is effectively forced to operate in secret as a result.
The issue isn't so much that characters don't die so much as whether or not their deaths would actually mean anything for the story. If the main characters' deaths are effectively ruled out by the trappings of the franchise, then the stakes have to be provided in other ways.
Civil War did this by making it so that the conflict stemmed not from a generic destroy-the-world plot but by having it be about personal tensions escalating past the point of no return. There's more to take away from certain characters' survival/returning than just "nobody stays dead so who cares what happens to anyone". Meanwhile, Gwen Stacy's death in
TASM2 isn't that significant in its own right - all it does is make Peter sad and remind him of his own shortcomings as a hero and a person. Why else do you think I used the word "
fridging"? Just because it's something that doesn't happen in other movies of its ilk doesn't automatically mean that it will be handled deftly or creatively.
The Marvel movies under Sony, at least have an element of tragedy about them.
lol, you don't need to tell me twice
The MCU itself is like watching the movie versions of Narnia... something tragic raises its head, but is miraculously reversed within 15 seconds.
Or watching a movie like Taken, or Olympus Has Fallen, or something Seagal would make... the hero gets something done to them which annoys them a bit, and they then goes on a relentless march of victory, bookended by hero shots and trailer moments.
What, like
RoboCop?
