Inception 2: why a sequel doesn't need DiCaprio's Cobb

Inception 2 doesn't need Leonardo DiCaprio. His story as Cobb is finished, and the better path for a sequel is to leave him behind, bring in an entirely new cast, and explore another corner of the world Christopher Nolan created.

Inception (2010) starred DiCaprio as Cobb. The whole point of that film was that Cobb was trying to get home to his children, and by the end, he finally was able to do that.

Cobb's ending in Inception shouldn't be undermined

Whether that ending is a dream or not doesn't matter, because the whole point is that Cobb has stopped caring. His arc is complete. He wanted to get back to his kids, and he did.

So bringing him back for another adventure, and undermining that iconic and still hotly debated ending, is a non-starter. Instead, a sequel should introduce an entirely new cast and explore another corner of this universe in a completely different genre. The only common denominator would be the world Nolan created.

Dream sharing in Inception supports an entire underground industry

Think about how enormous the world of Inception is. Dream sharing isn't some supernatural ability that only Cobb possesses. It's a technology that already supports an entire underground industry.

There are professional extractors who steal corporate secrets. There are architects who construct elaborate dream environments, and chemists who develop specialized sedatives. There are also experts who train people to defend their subconscious against intruders. And "the first film barely scratched the surface of what any of that means."

Why Inception isn't like Jurassic Park or Terminator

That's what makes Inception so different from something like Jurassic Park or Terminator. Those franchises have to keep finding new ways to recreate or reinvent the original premise.

Inception's premise isn't simply a group of thieves breaking into someone's dream. That's one story taking place in a much larger world. "Technology is the premise, and what you could do with it is practically limitless."
