Re: The Amazing Spider-Man
If this version can last long enough I'm open to a symbiote story over the course of two movies, idealy something like 4 and 5, work both Venom and Carnage in after Gwen's death at the hands of Goblin so Peter is in a very dark place emotionaly.
But I'd much prefer if they stuck to 1 villain or 1 major and one minor villain (green goblin / proto-goblin) per movie and built their way upto the Sinister Six.
If they could somehow plant the seeds for Brock in part 2, he could work in part 3. I just don't think it would happen that way. But at the same time, since they know this series will go at least three movies (based on Stone's contract), maybe they would be more willing to have part 2 as more of a second act, rather than an entirely standalone movie.
But also, just introducing Venom instantly opens the floodgates of sadness from SM3. So even if they had a good plan for him, SM3 would make me wary of Venom.
As for Carnage, bleh. He always seemed to just scream "90's Marvel" to me. Occasionally he was used well, but as an overall character I'm just not a fan.
I would love to see Mysterio, if he could be done well. And I'd like to see some other villains who wouldn't make a good main villain, like Shocker or Scorpion. They don't even have to have them as a big part of the story. Just show them near the beginning, getting beaten up by SM, as examples of how he now does this on a regular basis.
iirc, they showed that during a monolog that mentioned the many "loose ends" in Peter's life.
Yeah, along with the picture with his parents, Uncle Ben's picture, and one more thing which I'm now forgetting.
Rating was PG-13, not PG and not G.
