The biggest mistake this series made

And that they were bad films in general.

I hope that Tom Holland's Spider-Man films won't shy away from any classic comic book moments/stories just because the previous films did it first

Biggest mistake this series made was existing. Sony should have pressed on with Spider-Man 4 and 5. They would have made more money that way.

That's what happens when you reboot too early but at the same time, they could've gotten away with using Norman as the Goblin again. Raimi's Goblin wasn't that evil, granted he did some *beep* up things but he wasn't nearly as evil as he was in the comics. TASM2 should've went the satanic route with Goblin and throw in a couple of B or C List villains like Chameleon, Shocker, Sin Eater or they still could've used Electro and it would've stood out.

Or have a To Live and Die in LA type approach and have Norman terrorize New York and Spider-Man, kill Gwen and then shock the audience by killing him off towards the end of the 2nd act and have Harry become Goblin for the remainder of the film. Extremely risky and can easily backfire if not executed right but it also would've stood out from Raimi.

I actually kind of liked that the location of Gwen's death was different but the scene was close enough, that made it seem fairly surprising and fresh. But it was a big waste to have Harry rather than Norman as the Goblin and definitely to force him in at the end, probably better to not have included Gwen's death at all, at least so early on (I think the filmmakers may have admitted that the story felt too contrived to get to that ending).

Agreed that there's too much focus on Peter's parents. I sure missed the Daily Bugle.

The biggest mistake this series made is to EXIST. Here. Fixed it for ya.

The Amazing Spider-Man, despite its failure to excite the fanbase and its underperformance at the box office, was not a bomb by any means. So, naturally, work quickly began on a sequel. The Amazing Spider-Man 2 brought in Oscar-winner Jamie Foxx as new villain Electro, but the filmmakers didn't stop there. Seemingly determined to ignore the lessons learned from the overstuffed Spider-Man 3, the film also added Dane DeHaan as a new Green Goblin, and then there was a tattooed Paul Giamatti performing history's least-convincing Russian accent as the Rhino. The subplot of Richard Parker's death was also featured heavily, with the conspiracy now being tied to Peter's transformation into Spider-Man.

Perhaps the biggest mistake made by the film was the decision to kill Gwen Stacy. While the 1973 comic book story "The Night Gwen Stacy Died" is considered a classic, by the time the film was released in 2014, the plot point of a woman dying to motivate a male character was considered tired at best and offensive and damaging at worst. There was also a strong sense that the character's death was not earned in the film, and that it was done simply because death is what fans associate with Gwen Stacy. These confusing plot choices, as well as some subpar performances (Foxx and Giamatti were especially poorly received) led to both the worst critical reception and the lowest box office take of any Spider-Man movie up to that point. Clearly, something had to be done to again save Sony's biggest franchise.

One of the biggest mistakes they made was doing another origin story. They should have started with Peter already being Spiderman. The story with the lizard was fine. They made him almost horrifying and certainly the equal to Spiderman. It's like my problem with Spiderman 3. The story should have been only about Peter's fight with the Sandman, but not making the Sandman Uncle Ben's killer. Then do The Amazing Spiderman 3 - Venom
