Thus far, we have seen practically nothing from the movie throughout the curse of its production aside from a few pictures, and the constant shuffling of the X-Men franchise slate (which also includes The New Mutants) has caused alarm among some fans.
Nevertheless, it seems that the version of X-Men: Dark Phoenix that will hit theaters is still relatively close to the originally-envisioned storyline.
With all of that said, it is arguably not unreasonable to have gotten caught up in the fervor surrounding X-Men: Dark Phoenix and the massive potential changes that some people had assumed were happening.
