Amazing Spiderman 2 did the impossible and actually managed to outshit Spiderman 3. It copied that films most egregious faults, expanded upon them and shed off the few bright spots. To many villains. To many incoherent and barely connected plot lines. The script was just poor, with illogical and inconsistent motivations for all the characters and a nonsensical story. Spiderman 3 was bad, but it at least it had a few strong points like the sandman rebirth scene and the half aborted son of the green goblin storyline.
Amazing Spiderman 1 was a bland and unrequested offering, but was at least serviceable. Amazing Spiderman 2 collected as many hollywood names as it could and then filmed them all together as they took a collective dump on camera.
Honestly, Disney shouldn't pay a red cent for this franchise now. It was played out and pretty damaged at the end of Spiderman 3, but could potentially have been set back on track. After the last film however, the Spiderman franchise is becoming a symbol of hubris and incompetence. Another Amazing Spiderman movie from Sony and your average person will vomit at the mention of Spiderman in Pavlovian response.
