The bulk of their character arc is "son murdered", "they are very good at killing people", and "they are going to get revenge". Finally, Bayek and Aya are completely one dimensional in a similar way to Kratos in God of War, but unintentionally so.Again, the son shows up for a very brief amount of time during a forgettable mission and the short cutscene where he dies, and they expect me to have formed an emotional attachment? The son ends up feeling like a prop in service of the overall revenge tale, rather than a character I actually care about. The motivation for hating him is he killed your son, but you are never given a good reason to feel a connection between Bayek, Aya, and there son.
