Rose could have saved many lives, but chose not to
A Forbes article pointed out something I hadn't thought of, but should have been obvious:
The First Order has a tracker on just one ship, so they can only follow the fleet with that one ship. So why doesn't Leia order all the secondary ships in her fleet to jump to hyperspace and safety, leaving just the flagship in the First Order's sights?
The problem here is that Leia and Holdo don't know any details about the tracker. Only Rose does, although it's odd because Rose calls the tracker "new tech" and yet she seems to immediately know exactly how the First Order would use the new tech. There's no reason why, but she is definitely an exposition character.
After Rose "figured out" how the tracker is used, she should have run to her commanding officers and told them. That would have allowed a decision to be made to split up the fleet, sending all but Leia's ship in completely different directions, thereby saving all the other ships that eventually got destroyed. There really is too much "let's not share this critical information with the other Resistance peers on this ship" in Last Jedi. The Resistance is nearly wiped out due to an intentional lack of communication.
It's even worse when you consider how many variables Rose and Finn's "plan" hinged on. For one, it's necessary that the code-breaker be at the casino, gambling. Even if someone spends every waking hour gambling, out of an Earthly 24 hour day then you still need to set aside 8 hours for things like eating, going back to the hotel room, sleeping, and coming back. That example gives a 33% chance that the person won't be in the casino.
The plan also hinges on the gambler wearing his little flower brooch that Maz told them about, and who knows how long it's been since Maz last saw the guy. Does he truly wear it every day? What if he puts it down in a bet as a good luck charm and loses it to someone else since Maz last saw him? What if had gotten stolen?
Also, did anyone else think the code-breaker in the casino looked way too much like Poe? The two actors are extremely similar in appearance. share
