I wrote a short review about it before (note: spoilers from the movie are mentioned).
If you don’t want to read spoilers, I would say the movie covers the main conflict between the Assassins and Templars, but fails to delve deep into it despite “slow scenes” where they could have given a better explanation so audiences that never played the games wouldn’t be too lost or frustrate the fans.
I’m not entirely sure what you mean by “any future of the story.” If you mean if the movie will be mentioned in the games, then yes. It was confirmed that the movie is canon as it predominately follows the modern day story, but they would have to cover quite a lot of missing information that was not addressed in the movie if they decide to mention it in the games.
Also, I recommend reading the novelization of the movie after watching it (it’s written by the author that wrote Unity’s Employee Handbook and Blackbeard’s journal). But you might find yourself disappointed that a lot of information in the book didn’t make it to the final cut of the movie.
