The building sound effects greatly added to the anticipation and excitement on impending spine-tingling eventualities. Actors make up was done satisfactorily and not in exaggeration especially on the ghostly characters. Dramatic extreme close-ups on the actors presented audience the convincingly genuine emotions of the characters.
Costume Designer Joanna Johnston displayed an excellent job in adding to the establishment of the principal twist of the story. It may seem inconsequential at the outset but it was a very clever detail that Dr. Crowe oddly wore the same set of clothes throughout the whole film unlike the rest of the characters. The audience would certainly fail to notice that important aspect but once you get to understand the gist of the story and get the chance to view the film once again, one will be amazed by the designer's genius. Also in the part of Kyra's wake, there was already the suggestion of the mother being the perpetrator as she was the only one wearing inappropriately bright red outfit in contrast with the somber-clad family and guests.
Overall, The Sixth Sense is an outstanding film. But to truly enjoy it, it is imperative not to inquire for hints before watching the movie for it would certainly spoil the whole story.
