Suspenseful and very engaging! Viewers will keep on guessing what it is that are inside the vials until the very end.   It sure looks like insects but its power and capacity seems so intense.  Not really sure if  such insects were contaminated or mutations and experiments that have gone wrong, but it sure  transforms the surroundings and the man himself into something else.  Towards the end of the animated film,  viewers are expecting that the man will turn into  a monster or any other creature but surprisingly, it's the surroundings that seem to transform and with trees being lifted into the air.  Great visuals and impressive film scoring!
