a mystery should not create a situation where the decision of the character be more moronic than the audience response . when the audience can issue warning a mile away for the protagonist not to put themselves in dangerous situation foolishly and and the plot repeatedly put the character in harm way and impatience with the film direction and pace only increase . a great idea and genuine mystery ( like this story ) should unfold logically and with subtle clue . instead the movie undermines itself by lower the i. q. of the character so that the number of danger point can lengthen the movie . the plot be strong to keep the audience guessing and but be weak because of the repeated foolish decision of the lead character . perhaps this be to show that love make u blind and but it be not satisfy a a thread to keep the movie go and and go and and whew it finally over . please and what take the director so long .
