Well if you really wanted to get radical.
TFA is about the FO using Starkiller to resurrect Palpatine.
New Ep8 is TROS. Ends with Palpatine winning, destroying the Republic Fleet (instead of nobodies), and Rey escaping to self-exile on the island.
New Ep 9 is a recontexulized TLJ, rotoscoping out Snoke for Palpatine from ROTJ.
