Overheard in the theater at the end of my last viewing of TLJ:
Stranger to my left: "WOW, that was amazing, just perfect."
Stranger to my right: after a long quiet pause, “That was nothing like what i expected…”
I tell you, this just reinforces my personal belief (which could very well be wrong) that Expectations are a powerful thing, and most of the reason for the current fan ratings.
