Does Signs hold up?

August 2, 2002 aliens are invading Earth slowly but surely. There are signs all around us; crop circles, pops in radio frequencies, strange shadows in the night. Are they friendly or are they hostile? Audiences everywhere are eager to find out in the new suspense picture from M. Night Shyamalan. We follow the Hess family as they search for answers to what the aliens want, but we ask the question...Does it hold up?
