One thing I haven’t seen brought up yet is how the Rey-Palpatine lineage now makes TFA absolutely, hilariously coincidental.
The map to Luke is discovered on Jakku by an old friend of Luke’s, and the first person BB-8 carrying the map runs into is the granddaughter of Palpatine, who is in speeder distance of the Millennium Falcon and happens to use this to escape the planet and they happen to be picked up within five minutes by Han Solo and brought to a place that has Luke’s old lightsaber in the basement. All of these things, save the connection between Han and the Falcon, are complete coincidences.
