That's very debatable. In fact most came away with a completely different impression, that what was telegraphed hard was Kylo's permanent fall. That what they hit you on the head with was the misdirect. That the speech at first glance seemed to invoke that he wanted to turn back and was having trouble going through with it. When what it actually meant is that he wanted to kill his father and complete his turn but was having trouble going through with it. Turning it back around in TROS was then major back-peddling.
