Once again another frustrating mediocre produced presentation !Don't get me wrong the effect and handling seem great the problem is the explanation ! whom ever shot this as well as the presenter were not taking into account camera distance,remember the reason we buy these effects is to immediately understand what's being presented & if visually one has to decipher through Murky proceedings then what's the point !a body shot is Unnecessary when a close up of the hands is appropriate for comprehending the sequential order & structure of the effects handling & procedures the whole experience was so frustratingly exasperating that it drove me to drink for four & a half days !Mr Devlin please re shoot a proper presentation its worth the effort !I'm giving this 5 * for the concept but in terms of production it would be below Zero !Now that's Cold !
