this be without doubt the most exciting and satisfying film i have see in year . the plot see in print be almost banal a ship crash on a desert planet with three sun and the survivor have to adjust to the landscape and each other and then darkness fall and the monster appear . pilot fry and after a moment of cowardice during the descent through the atmosphere when she almost jettison the passenger and take charge of the group and enlist the help of convict murderer riddick to lead them through the darkness to the escape ship he the one with surgically enhance eye that can see in the dark . but it really not that simple every character be complex and three dimensional and with conflict trait so you never quite know who good and who bad . the performance be uniformly superb radha mitchell show fry steel herself for leadership and overcome her own fear and and try to prevent far bloodshed and while cole hauser and a the man take riddick back to custody and show he have his own agenda and his own idiosyncratic standard . but the film belongs to vin diesel a riddick he have the most magnetic screen presence i have see in year . for much of the film his face be in shadow and and he doesn not actually say a great deal and but he draw your attention all the same . sometimes he draw your attention by not speak or by not move . and diesel doesn not trivialise the character and as could so easily be do and by give him a heart of gold riddick be still one mean and vicious man a they approach the ship he just let u glimpse those first tentative step from care only for the self to care for others . technically the film be very good . the lighting effect be excellent at both end of the spectrum the overbright triple sunlight and the pitch darkness . special effect show both riddick and the monster point of view add to the suspense and a do sound effect of the monster fly and use ultrasound to see ( the monster themselves be anatomically plausible and suitably frighten ) . editing be so tight it almost jar at time there be literally no padding in this film and no fade and no time to re orient yourself . from the opening shot to the end of the credit you have to keep your wit about you . every scene and every line of dialogue and every single camera shot be important . see it three time to understand it all . my only caveat be about the science the solar system a show in the model be impossible ( planet revolve around sun and not vice versa ) . however and that doesn not affect the human story and so i haven not take point off for it .
