The reason to record this one
This trailer was made to be reacted to
Drama trailers earn their reactions quietly: a line reading, a look, a cut to black. The small moments land hardest on camera.
Every theatrical release wants the same thing: a real reaction before the reviews show up. Yours can be first.
