New York Times:
With slapstick smothering the scares, "[REC 3]" is further marred by a plot in which the muted Catholicism of its antecedents is turned up to full blast.
It's hard to maintain dread while the filmmakers are so obviously grinning at their own cleverness.
"Zombieland" and possibly "Shaun of the Dead" aside, this isn't a genre with a lot of life in it.
New York Post:
Plaza throws in more than enough ludicrous touches of his own to grab viewers by their arteries and never let go.
For all its gleeful limb-severing, offal-scoffing and chainsaw-wielding, this disco mirrorball of a movie scatters ideas in all directions, rather than focusing the spotlight on what counts - the scares.
Giddy shots of the undead slogging through a decimated party-scape materialize the decadence and instability of upper-crust family life, even as groom and (pregnant) bride prepare to give birth to another generation of the Spanish elite.
