Not huge things, but I also wasn’t really a fan of 1) First Order spies being there, 2) a Resistance spy being there, and 3) Finn seeking transport with a couple guys like Ben and Luke were trying to do in ANH.

I actually thought that was a really clever way to show us that the Resistance and the First Order are on a pretty equal footing in the galaxy at this point in history. That is as apposed to the OT where the Rebels were a small group of freedom fighters, and the Empire spanned the galaxy. Now, thirty years later, they are two more or less equally sized military forces, each with their own spy-network.
(It’s also a decent plot-reason for having the Resistance show up to save the day during the FO attack.)
