The big thing about Force Awakens I missed was the advances in technological film making. That was always George Lucas most important contribution to film. He always raised the bar.
Edit: the internet says 4 minutes
Movies like Jurassic Park and Independence Day that came out before the prequels (well before, in the case of JP) that used a blend of models/animatronics and CGI looked way better. The visuals in Ep. 1 were an obvious step backward the day it was released, no hindsight required.
