derek jarman have show u time and time again that dialog be not his strong suit . he be a painter and and paint he do . his film be almost always visually splendid and but about as exciting to watch a paint that be already dry . watch his movie in fast forward and the really fast setting that you can only get on dvd . in the tempest and jarman do very little with the script or the character and use them a simply a lattice to hang a very long and well construct cinematographic frame . he even go so far a to contradict shakespeare original script to achieve these excrucriatingly slow and lifeless scene . there be none of the romance and magic and trickery and or urgency the script call for and little spontaneity and and the character of caliban in particular be reduce to a quivering and insane idiot of sort and similar to gaveston in jarman edward ii . it be too bad that this be just about the only film version of the tempest available .
