“Ambition” (** out of four) was a jumbled thriller about an aspiring musician (Katherine Hughes) preparing for a competition who gets involved in a brain-twisting scenario involving her boyfriend and another friend (Jared Bankens and Giles Matthey) involving deception and murder. Very stylishly directed by New Line Cinema co-founder and CEO Robert Shaye but story is uninvolving and cold and thus has little impact. Ambitious, to be sure, but still too slight and too tepid to recommend.
