Depends on the type of filming being done I guess.. If its dvd-ripped or taken straight as a recording from the TV there shouldn't be, However if you find volume mostly being in the background it may be that people were talking in the background when the special was recorded. I didn't notice it myself however upon watching..
GREAT Special
Once again Ninomiya Kazunari makes me cry my eyes out in a special he has done.
Thought Door to Door was bad, This probably had me crying even more.
It was really moving, While Door to Door showed you how much suffering a disabled person has to go through,
This showed you lots of the kindness people offer the ones who need it along with the storyline.
I really loved Yasube here, Such a great role..
Once again a Kazu-chan role fails to dissapoint me.. <3
A touching movie, It wasn't boring for a minute..
