“InstaPsycho” (** out of four) was a pretty predictable teen cyberthriller about a new girl in school (Kara Royster) who is framed for murder by her cliquish best friend (Mackenzie Vega) who uses social media and online information to scheme her way to the top but the other girl attempts to turn the tables on her and prove her innocence. Not bad as far as these things go, with decent acting and film-making, but not original or surprising by any means. “Mean Girls” more-or-less told this same story (minus the murders) far more wickedly and hilarious nearly 16 years ago.
