Precisely what Centaurus is saying. This is not CRM or "coordination", this is just a technical skill stuffup, plain and simple.
Would you really expect the crew to have a committee meeting (good CRM) to discuss what the FO had just done? Of course not. CRM is working together to solve a problem/FOs being empowered to speak up/Captains listening to their crew. However, one of the most basic requirements of good CRM is that each member involved is technically skilled in his/her job. If someone stuffs up in the hypothesised manner and the aircraft crashes immediately, it's not a CRM failure, it a technical skills failure.
Note: I am in no way implying that the Lion Air crew made any errors. My comments on CRM are general in nature using the example mentioned.
