Assassin's Creed.
What I will say about this film is that it is made for the fans of the video game series as it stays mostly true to the series' mythos. If you've never played an Assassin's Creed game, I would not recommend seeing it as you might find yourself confused about the plot. As for the film's story, it was quite slow in the beginning but it does pick up with plenty of action. The ending seemed to imply that there will be a sequel.
