Lower Level

Hillary begins seducing Sam, distracting him and allowing her to stab him in the back with a piece of glass, giving her the chance to escape and reunite with Craig.

The two try to escape from the sealed building through a tunnel in a storage area, but they find it blocked off, and so are forced to try and fight Sam off, which they do by luring him into a trap that leaves him hanging upside-down from an elevator.

Joe Kane, author of The Phantom of the Movies' Videoscope: The Ultimate Guide to the Latest, Greatest, and Weirdest Genre Videos, called the film "a down-scale Die Hard" and gave it a grade of 2½.

[1] TV Guide awarded Lower Level a score 1/4, and found that while it was "glossy" and excelled in its use of sound to build suspense, the film was ultimately brought down by both its severely padded plot and "the cast behaving like idiots to prevent the tale from finishing early or logically".

[2] Empire gave the "enjoyably contrived" film a 2/5, praising the effective suspense sequences, yet criticizing the uncharismatic leads that prevented it "from achieving its potential".
