I think the movie would've been better if the twist had been the main protagonist was actually an AI herself without knowing she was and was inadvertently behind everything. The actual ending was kind of disappointing. Otherwise I don't understand the bad reviews. Sure it's a B-movie, but if you're into computers, technology, coding etc., you'll be entertained. As far as her neck mannerism, I think she's just supposed to be a very tense person. She reminded me a lot of Nebula in Guardianf of the Galaxy,
