Maybe I'm reading different things into the argument. I don't think that anyone is saying these movies can't be or shouldn't endeavor to be serious. The problem is shoehorning dark seriousness into a character, setting or story that doesn't need it in a cynical attempt to make the story more "realistic."
I'll use Man of Steel as an example because my dislike for Amazing Spider-Man is a bit too fresh to be completely objective about.
Superman struggling to come to terms with his powers and identity is a good seed for a story. Humanity being distrustful of an alien super being and him having to earn our trust is a great seed for a story.
Man of Steel put these seeds on on display and then never planted them. It spent 50% of it's run time giving us dour flashbacks into Clark's dirt farming childhood as one long string of miserable super-accidents. This would have been a great setup for his hesitation to reveal himself to the world but didn't pay off at all because he's never really given a reason to.
It wastes so much time being Super Serious and Super Miserable that when it comes time to actually be Super Heroic we've hardly established a good rapport with our protagonist. The end result is Superman never doing anything to gain the trust of humanity as a hero and never really establishing a connection to humanity that justifies his outing to the world.
It's a miserable movie without a shred of optimism to it and it's just exhausting to watch.
