[REC] 4 Apocalypse (2014)
The last one in the series. This takes us back to the apartment building from the first 2 films, with the original news anchor to boot. It also completely ditches the found footage element. So calling it [REC] is a bit of a stretch at this point. To fulfill the small set requirement, they move from the apartments to a boat.
It’s your typical zombie movie from here on out. Complete with a sinister organization that is trying to study the freaks for their benefit. On a boat!
