We don't know if that's why they cut stuff that was in the trailer.
TFA is a really good film but it still irritates me that Kylo walking through the forest and activating his saber was cut. So if there are a bunch of stuff from the trailers that I like that ended up on the cutting room floor it's going to irritate me regardless of the overall quality if the film. Especially if I prefer take or moment that was in the trailer compared to what they put in the film. One example of that happening is TDK. A number of Ledger's takes were different in the trailers and I think they were better than the takes that were used in the film. It still irritates me to this day.
