The AI in Chappie is not malicious or hostile, but it has some badly skewed ideas about how to interact with people, probably owing to being "raised" by South African drug-dealing gangsters. Chappie is a very non-Hollywood movie, which is probably why the reviews are so polarized (folks seem to hate it or love it, with little in between).
Remember that CHAPPIE is brought to you by the same director, Neill Blomkamp, who gave us DISTRICT 9 (2009) and ELYSIUM (2013). Small wonder that it has a decidedly non-Hollywood feel to it.
