The only real gripe I have with the movie is that Chris Pratt and Jennifer Lawrence have zero chemistry, which kind of kills the whole romantic element of the film.
That actually helped make the movie more plausible. Pratt’s character knew almost nothing about her, but formed an opinion and love based upon what he wanted her to be. She wakes up, and is (surprise!) an actual human being with thoughts and feelings of her own and very little about what Pratt’s character projected onto her. At the same time she’s dealing with the struggles that the only other awake human is essentially her murderer, and for her to find some other human to connect with, she’d have to perform the same egregious act on someone else against their will.
It felt like a struggle from before our modern age where a woman might have to marry someone she doesn’t even like to make sure she has food, shelter, power, etc. She came to terms with her situation and made of it what she could like millions of women before her in a world dominated by someone else.
