How do you feel about the coincidences in the OT?
There were indeed coincidences in the OT, especially Star Wars, but they seem to be of another kind. There was a reason for Ben and Luke to be in the same area on a desert planet, since Ben was watching over Luke. There are potentially good reasons why the Droids land near Luke and Ben, since they could have Ben’s coordinates and were piloting the pod in that direction (as the Radio Drama suggests). In Empire, Luke’s sensors die and his ship crash lands on Dagobah within walking distance of Yoda, which seems like a terrible coincidence. However, since it is established that Yoda can manipulate things even as large as X-wings, he could have brought Luke to his location through the Force.
However, there’s no given reason for Rey and Tekka to be in the same area on the desert planet, if Rey is indeed Luke’s daughter or has ties to the Jedi. It’s a coincidence of a different order, and then there’s the compounded problem of her working at the same outpost where the Falcon is stored. The odds of these three things all being found within walking distance of each other in a vast galaxy strains credulity to the breaking point. Then we have Rey just happening upon Luke’s old lightsaber. This shattered my immersion the first time I watched the movie. The very fact that his lightsaber was not lost on Bespin requires a explanation that Maz acknowledges, but we’re so caught up in how odd that is that we may forget that her stumbling upon the saber on one spot on one planet among millions of planets is wildly implausible in the first place. It is as if in Star Wars, Alderaan wasn’t destroyed and Obi-wan took Luke to one of his old haunts on Alderaan, and the bartender said ‘Oh by the way, here’s Anakin’s lightsaber’ and Obi-wan said ‘how did you get that?’ as if he didn’t know that Anakin was on such good terms with the bartender. I would use the cantina from Star Wars as the example, but keep in mind that Maz is on an entirely different planet that as far as we know, only Han visits among our three old heroes.
