REC 4 opens as army doctor Guzmán (Paco Manzanedo) and soldier Lucas (Críspulo Cabezas) rescue TV reporter Ángela Vidal (Manuela Velasco) from the apartment block where the original movie took place. The trio are put on a quarantine ship where scientists conduct experiments into creating an antivirus. However, the true nature of the infection means that it isn't long before the survivors are running for their lives from drooling, crazed, flesh-hungry 'zombies'.
Part 3 of the REC series had quite a lot of detractors, but I enjoyed it for its refreshing change in approach, which saw the introduction of a touch of humour and a lot more splatter. REC 4: Apocalypse is a return to the dark, claustrophobic atmosphere of the first two films (but thankfully, with minimal found footage style camera-work); as such, it will be seen as a welcome case of 'back to basics' by many, but to me it felt very predictable, and, as a result, less satisfying. I also found the gore lacking and was surprised by how few scares there were.
Oh well, at least director Jaume Balagueró had his heroine strip to a tight white vest and got her good and sweaty for the finalé (sometimes, it's the simple things in life).
5.5 out of 10, generously rounded up to 6 for IMDb.
