- Broken Base:
- The end of the first film briefly split the fandom between those who liked the Religious Horror twist and those who didn't, but hoped that Father Albelda and the Vatican had just confused a zombie virus with the effects of demonic possession. Word of God and the second film extensively confirmed that the infected were actually possessed.
- The end of the second film then split the fandom again, between those who liked the demon having a worm-like form and being able to possess Ángela, and those who didn't like either.
- The whole third film. Some liked that it abandoned the Found Footage aspect, original cast, setting and story before they got stale, and others hated it for exactly the same reasons making it an In Name Only sequel. Other sources of contention were the change of genre from pure horror to a Horror Comedy in the vein of Evil Dead or From Dusk Till Dawn, and changing the infected themselves from Nigh-Invulnerable to more standard zombies (or weaker than them, as the ones in the film can be killed by being shot in other places than the head).
- The fourth film, largely depending if the viewer liked the third film or not. It was the return of Ángela and the worm demon and a less comedic tone (though the film feels more like an Action or Adventure flick than a straight Horror, and there is no first person perspective either). Many on both sides would agree that the film is a weak ending to the franchise in any case, however.
- First Installment Wins: The first film is unanimously admired by critics and fans. The sequels... not so much. Especially parts 3 and 4.
- Ensemble Dark Horse: The firefighter in the second film is this due to the fact that he slaps one of the annoying teenagers in the face which is satisfying along with the fact he calls them out for being idiots and that he along with Jennifers father are the only ones who are not arrogant like the GEO operators and Owen or idiots like the teenagers making him the Only Sane Man of the protagonists in the second film.
- Memetic Mutation: "Pablo, grábalo todo. Por tu puta madre"*
- Nausea Fuel: Medeiros vomiting the demon itself, a grotesque worm-like entity, into Ángela's mouth.
- Too Bleak, Stopped Caring: The biggest complaint of many fans with the second film: the GEO operators and "Dr". Owen fight over the entire film, and the arrogant behavior of several of them does not help the situation; the teenagers who appear halfway through the plot are annoying and have no idea what situation they are in; and the only survivor of the first film, Angela, turns out to be in the end possessed by the virus. Adding to this the Downer Ending of the film, it is not surprising that many fans question why they should care about these characters.
YMMV / [REC]
