Marc Webb's The Amazing Spider-Man would be a decent movie if it had nothing to do with comic books. When left to his own devices, Andrew Garfield gives Peter Parker an agreeably sardonic side, at once cocky and anxious as he spits out the quips sorely missing from Sam Raimi's post-9/11-tinged idealism. Garfield even enjoys ample chemistry with his leading lady, Emma Stone, which is a nice change of pace, not merely from Raimi's films but the superhero genre as a whole. Were the film nothing more than a slightly surreal abstraction of pimply and emotional hormone changes, it would make a fine romantic comedy powered by believable actors doing above-average work.
But this is a Spider-Man film, and the hormonal abstract in question concerns Parker's superpowers, which themselves entail a narrative arc of responsibility that generates the greatest tension of Parker's life. A good Spider-Man story is less about the fight between Spidey and the chosen villain than how his constant quest for a normal, happy life must be sacrificed for the greater civic good. That tension is wholly lacking in Webb's version, which recalls Green Lantern in its cynical rewrite of a noble character into a self-absorbed narcissist who always makes sure to hedge his bets on even the most tentative of mature actions so he ultimately emerges the same erratic jackass at the end of the film he was at the top.
