Oscar Isaac's Star Wars character of Poe Dameron is a good looking, hotshot pilot, and since the saga is now missing the original character that filled that role, it leads one to wonder if Poe Dameron is going to take a Han Solo-like role in the new trilogy. The actor says that Poe won't really be able to become a dashing rogue, as he has more important responsibilities in front of him. According to Isaac...
I think what [The Last Jedi director] Rian [Johnson] did was make it less about filling a slot and more about what the story needs. The fact is now that the Resistance has been whittled to just a handful of people, they're running for their lives, and Leia is grooming me --- him --- to be a leader of the Resistance, as opposed to a dashing, rogue hero.
While Poe Dameron had the least amount of screen time of our big three heroes in Star Wars: The Force Awakens, he nonetheless became popular with fans, something which is good, since he was originally supposed to die early in the movie. While none of the new trilogy heroes are perfect analogs for Luke, Leia, or Han, Poe certainly had his share of Han Solo-like qualities and was probably the closest to him of the major characters. However, Oscar Isaac tells Esquire that Poe will be taking a very different path from the loveable scoundrel.
From what we've seen in the trailers and heard in rumors it appears that Star Wars: The Last Jedi will open with the Resistance receiving a major attack from the First Order. This attack splinters the Resistance and put them back on the defensive. It sounds like General Leia knows that the organization could need a new leader at any moment, and thus is preparing Poe Dameron to take on that role if and when it's needed.
This could give us a pretty significant glimpse into what's in store for Poe Dameron, not just in Star Wars: The Last Jedi, but also Star Wars: Episode IX. Since we, unfortunately, know that General Leia will not be leading the Resistance in the final film of the trilogy, it stands to reason that if Poe is being groomed here, he'll be moving into that position in the final film.
Clearly, this separates Poe from Han Solo in a very significant way. While Han did eventually become a major member of the Rebel Alliance, some fool made him a General, the fact that he eventually left entirely shows that he was never going to be the leader type. We'll get to see this transition for Poe when Star Wars: The Last Jedi hits screens next month. If you haven't pre-ordered your tickets, you may want to do so now.
