I mean, I've seen the movie a bunch now, and I surprisingly don't have strong thoughts about Starkiller Base or that scene, since they both seem like means to an end to get Rey's, Finn's, Kylo's and Poe's (in the most rehashed, familiar way of the four) to resonant places I really like.
I have thought over time that from a storytelling perspective, the base really should've destroyed Jakku. I know it might not have been in the same system for them to see like Han does in the scene, but what better way to motivate and develop Rey's character at that point (when the script would've already generally had her as a mess from her lightsaber vision) than to give her no home to go back to? The only other speaking character we know there is Pegg's villainous pawner (and in not exactly canon deleted scenes we even see he made it off of Jakku to get to Maz's tavern planet).
