Oscar-nominated director M. Night Shyamalan is back with the highly anticipated follow-up to his directorial debut, “The Sixth Sense.” His new film, “Unbreakable,” reunites Shyamalan with Bruce Willis to bring forth the same sort of quiet intensity that characterized “The Sixth Sense.”Willis, known mostly for his more sarcastic charm in action-packed films, has taken a step away from his norm to portray a more human character. His last few films such as “The Story of Us,” “The Sixth Sense” and Disney’s “The Kid” have showcased this more vulnerable side of his personality.He takes on the same tone in “Unbreakable,” portraying the emotionally confused character of David Dunn. A deteriorating marriage, a lackluster job and a feeling of no purpose in the world has Dunn at the crossroads of life.A catastrophic train wreck which leaves Dunn as the sole survivor instigates a series of events that lead Dunn to his ultimate purpose in life. Enter Elijah Price (Samuel L. Jackson).Price was born with a disease that left him highly susceptible to bone breakage at the most minimal of slips or falls. He figures that if he is the type of person to be so fallible, then there must be another person on the opposite end of the spectrum who is “unbreakable.” Learning of Dunn’s escape from death, Price seeks him out to pose an answer to the phenomenon. That possible explanation causes Dunn serious internal turmoil as he struggles to first deny, then accept, the chance of it being the truth.Saying much more would only increase the chances of giving away the surprising ending. Much like “The Sixth Sense,” this ending is one you might have expected, but when it happens, still shocks you. Shyamalan’s script is a complete original. The premise for the film is incredibly innovative and it is exciting to watch it unfold. The beginning may confuse you a bit, as a historical background of comic books set the stage. Nevertheless, the interweaving of the comic book theme and its astonishing ending are a credit to Shyamalan’s expertise as a writer.While “Unbreakable” encompasses many of the same cinematic and situational elements of “The Sixth Sense,” the two ultimately differ in regards to the pace of the film.”Unbreakable” is slow throughout the first hour or so. It only begins to pick up in the last 30 minutes as all the pieces start to fall together. It is an extraordinary movie within that last half-hour, but the sluggish beginning overshadows the end appeal. While the content of the movie may suffer a bit from a slow-moving script, the technical aspects of the film are incredible. The intricate attention to detail from lighting to props is amazing. Shyamalan also has the great skill as a director to bring out depths of emotion in actors that you have never seen before. Already mentioned, Willis does a brilliant job depicting the range of emotions needed to play David Dunn. Jackson does an exemplary job portraying a man that silently pleads for compassion and at the same time makes your skin tingle with his creepy demeanor.Robin Wright Penn also gives a wonderful performance as Dunn’s wife, Audrey. Spencer Treat Clark gives a convincing performance as the son, Joseph Dunn. While he is no Haley Joel Osment, child actor Clark does a first-rate job.”Unbreakable” is a very entertaining watch if you can just get past the lethargic beginning.
