To those inclined to think in such inartistic terms, a [REC] movie must hit certain notes, carry a certain tone and look, and develop in a certain way. What modern audiences appear to want out of a sequel is the exact same experience they already had the last time.
One must judge what it is, not what it isn’t.
So much for social responsibility!
Therefore, I applaud Paco Plaza and the other filmmakers for playing out a fun variation on a theme, instead of merely grinding a familiar, well-worn theme to death.
