“M3gan” (** out of four) was a jumbled horror thriller about a brilliant robotics engineer (Allison Williams) who gains custody of her niece (Violet McGraw) and then builds the title lifelike doll for her to protect her and be her companion but naturally things go horribly wrong when the doll develops a mind of her own and becomes overprotective and savagely violent. Yet another movie about artificial intelligence that feels artificial and doesn’t have very much intelligence; film is a derivation of Spielberg/Kubrick’s “A.I.” and also “Annabelle” and “Child’s Play” and is only made for those who’ve never seen any of those previously. James Wan was one of film’s producers.
