It's funny that Assassin's Creed was mentioned as being too close to the game, but I thought it managed to miss most of the major points of the game series (which wasn't super complicated to begin with).
I mean, it doesn't even succeed at convincing the audience they should root for the Assassins instead of the Templars.
It's like they assumed everyone who was watching who didn't already know the story would be too stupid to understand it.
