You could be afraid that the last chapter of the saga 'official', that since the original intent of the George Lucas , decades ago, had to quit Star Wars, was flooded by the need to close them all (and instead, of course, much remains open, and is a spin-off series continue to swarm around the nine Main Texts). Apart from allusions, references, plots, the plot is very simple. The evil emperor Palpatine is back, pulls the wires from a planet unknown. The Jedi Rey ( Daisy Ridley ) and the pilot-in Poe ( Oscar Isaac ) they must find him and defeat him. In the meantime Kylo Ren ( Adam Driver ), after having tried in vain to bring Rey to the Dark Side of the Force, it should be in a crisis of conscience.
