The case for reacting
This trailer was made to be reacted to
A thriller trailer plants a question in the first ten seconds and spends the rest refusing to answer it. React to the wait.
Theatrical releases are won in the weeks before opening night, and trailer reactions are where that energy starts. Yours can be part of it.
