Now I'll be the first to admit, I don't play Assassin's Creed for the story. It's preposterous, I understand. But this seems like a complete setback for the franchise altogether. Co-produced by Ubisoft themselves, they really have no one else but themselves to blame for this movie turning out like it did. The reviews are still early, sure, but I don't really see it skyrocketing from here.
I think they just sealed the fate of the company's independence at this point.
