After a fight gets out of hand a group of friends run for cover but find themselves fighting for their lives against ravenous creatures lurking beneath their rave party.
Over dramatic, low budget horror flick that has some fantastic makeup and special effects in amongst the unnecessary fights,hammy dialogue and slow motion scenes.
Underground starts off very promising with the opening of an army squad fending off some nasty looking super genetic humanoids, then director Rafael Eisenman introduces us to an underground rave in an air hanger on a military base that goes on far too long. Underground's weakest link is that it's not very tight and scenes are drawn out. It's well lit and shot with some good pumping tracks.
The score is a mixed bag there's some great music cues but then it borrows from familiar scores and overcooks them. Writer Charles Morris Jr. borrows heavily from Marshall's Descent (2005) and Smith's Creep (2004). The young cast of actors including Eric Abercrombie and Mira Antonova do there best with the script. The Eli Wallach with a German accent lookalike aside - there's some nice touches, a creature bursting out of an urinal, torn off ears, lobbed off arms, spooky tunnels and creepy corridors.
A lot of effort has clearly gone into Underground, it has a 'film' look and with some tighter editing it may have helped the viewing experience. Rafael Eisenman uses every film trick in the book and clearly has ability but it just isn't a polished enough production, nevertheless it's a lot bloodier, effective and atmospheric than the abundance of cheap looking horror DTV films.
Despite it's unevenness there's worst ways to burn a hour and a half.
