Lucy is a Mary Sue and has no place in this movie

I wouldn't have mind Lucy if they were realistic, but they made her too much plot armor. Had they just killed her off in the first combat scene in the bedroom, then it would have been realistic and perfectly fine. This continued to happen throughout the entire series. She continued to live rather than die. They are treating her as if she's the hero. How can anyone watch this and not be disgusted by the woke propaganda?
