The writing is poor and the plot is filled with clichés and stereotypes, but there are people who take it seriously

>She has a clear personality a full backstory and is recognizable by her characteristics.
She doesn't, she doesn't, and she's not. I can copy and paste ellen page too, that doesn't make any of those things true. Samus isn't really a good comparison because her games are about game play, why obsess over that one? She was never meant to have much of a personality, Elli's game however has terrible game play, broken AI and generic level design. She needs to be better written and right now she's just disappointing.
