it's Harry Potter for me BUT i was really disappointed with the ending in the movies.
in the movies:
harry + voldemort go running around the castle hitting spells at each other, harry pretends he is going to give voldemort a hug then pulls him off the side of the castle, they go for a nice little flight around the castle. they land in the courtyard, are on their knees, and both their wands connect so they both try push their spell towards the other.
harry then overpowers voldemort who then just turns into bits of snake skin that disappear into thin air. his body is completely gone and everyone has to take harry's word for it.
in the books:
after harry is revealed to be still alive everyone starts fighting and everyone gets pushed into the great hall. eventually harry + voldemort confront each other. everyone else is standing around them watching.
both harry/voldemort circle each other while harry explains how voldemort has failed and that he can't win. he calls by his real name Tom and gives him a chance to feel some remorse but of course voldemort refuses and goes to kill harry who then disarms him. voldemorts wand comes flying towards harry and the killing curse strikes voldemort dead. everyone in the hall witnesses his death and his body doesn't disappear. his body is put in a room away from all the other dead bodies.
voldemort was afraid of dying and that's why he wanted to become immortal. having him die like any other human is such an important point. also having his followers witness the death means they wouldn't say oh he'll come back. he died like a human and was probably buried or cremated. i'd absolutely love it if he was buried in the same grave as his father who he hated.
