For me it’s definitely everything that happens between Finn and Rey meeting Han and Chewie and their escape on aboard the Falcon. The whole sequence plays out like some sort of farcical slapstick with the stupid rathtars and the space gangs, I felt as if the movie turned into a parody of itself.
A close second would be the conversation between Anakin and Palpatine in the Opera house. Seriously, this guy with no apparent ties to the Force is revealing himself to be very knowledgeable about the Sith and talks a great deal about how the dark side is better whilst making no effort whatsoever in hiding his contempt for the Jedi and Anakin, a Jedi Knight, does not find it the least bit suspicious, instead calmly listening to everything he says.
