New York Times journalist Brooks Barnes joins guest host Wab Kinew to discuss how some movie theatres are shaking, spraying and otherwise stimulating audiences in an attempt to attract a younger demographic.

Brooks explains that 4DX theatres are the industry's latest weapon in the big screen's losing battle against a plethora of smaller screens -- especially when it comes to smartphone-touting teens and 20-somethings.

The critic walks through a list of new sensations -- strobe lighting, smoke effects, odours, bubbles, back vibrations and leg ticklers -- and shares why older or more traditional movie lovers may want to avert their eyes.
