A gang of druggies are arrested after having the cops called on them by the superintendent of the building they were squatting in. After being released by the cops, they return to seek revenge, taking the building floor by floor and killing anyone in their path! Now this is an awesome plot, and sets up for a shit ton of fun. The gang is comprised of a motley assortment of different baddies, with the ultimate bad-ass Chaco leading the pack. They each feel authentic and intimidating, but I would have preferred if Chaco had remained silent as a mysterious background character. The film is drenched in blood and gore, rightfully earning it an 'X' in its initial theatrical run on the Grindhouse circuit. While the premise, action, and gore in the film all make for a great Exploitation classic, one cant overlook the terrible filmmaking and acting that come with it. There are many over the top and cheesy performances (mostly from the tenants) mixed with a range of film goofs, sterile directing, and cardboard camera work that make the low budget all too apparent. The pacing is also hindered by uneven action and plotting that loses focus at many points throughout the film, taking several unnecessary sidetracks that only serve to distract the audience and pad the run time. This is definitely a film that could benefit from a remake with a more competent director behind the wheel, but it makes for a great watch and comes recommended!
