What's happening to M. Night Shyamalan?
I remember a
              young, hotshot director who provided the most memorable twist ending of
              the 90s in "The Sixth Sense" (technically his third film, but his first
              big thriller). His next projects were worthy follow-ups "Unbreakable"
              and "Signs," the latter of which is particularly underrated as a
              family-friendly hair-raiser. 
Then things went awry. Horribly, jaw-droppingly awry.
Whereas Shyamalan used to genuinely terrify with his ending
              revelations and atmospheric tricks, he seems more concerned with the
              shock value of his story than with harder-to-earn chills. Watch closely
              the scene in which a woman shares her digital camera footage of a
              zookeeper's last moments in a lion cage. Compare it to that well-known
              instance in "Signs" where we catch a glimpse of an alien through
              someone's home movie. You'll see the difference.
Wahlberg's
              performance is not a good one. He comes off as raspy, whiny, and
              generally miscast as the young teacher protagonist. Shyamalan doesn't
              help by lingering on his actor's befuddled face in close-up far too
              many times. He looks like a lost kitten trying to get back home (for
              Wahlberg, grittier, more intense roles).
