Critical Mass is yet another version on Die Hard (1988) and the basic plot template it created of a lone individualistic hero inside a large building/facility single-handedly fending off a terrorist plot. There are a surprising number of similarities between Critical Mass and Project Shadowchaser II/Night Shadows: Project Shadowchaser II (1994), which featured Bryan Genesse as a janitor in a nuclear plant, defending it as it is taken over by an android terrorist. Take away Frank Zagarinos android (which was never properly explained anyway) and Critical Mass and Shadowchaser II would be virtually indistinguishable.
The similarities to other films do not end there. Fred Olen Ray frequently populates his genre films with in-jokes, lines and character names that refer to classic genre films. With Critical Mass, he has gone to the extent of actually incorporating material taken from two other films. In this case, he has somehow managed to acquire copyright to action sequences from Terminator 2: Judgment Day (1991) and Universal Soldier (1992) namely the opening raid, which consists of the attack on Cyberdyne Systems from Terminator 2 (he has even left the Cyberdyne sign in, which is prominently featured in the first shot), and the scenes of the buses buzzing around in the desert from Universal Soldier. If the footage was not obvious to any action movie fan, then surely the fact that these are the only decently scaled action sequences in an otherwise eminently forgettable piece of hackwork would give the game away.
There is very little to Critical Mass other than lots of routine running around the facility and shooting people up. Perhaps the one interesting thing about Critical Mass is the clear political agenda that comes through. Fred Olen Ray is clearly someone on the Republican working mans side and despises liberal politics. The senator throughout is portrayed as pompous and self-important. He takes a stand on liberal issues but is clearly exploiting the issue of the plants closure and the loss of jobs for personal political gain. Treat Williamss blue collar working man is given to be Fred Olen Rays voice, dismissing the issue of job loss with a shrug, saying that he (ie. the ordinary working man) has been prepared for it and is not worried, while the only people who are likely to be affected are the scientists who can easily get jobs elsewhere. It is an attitude that takes one back and makes stiking contrast to the way real-life plant closures have affected entire communities. Try contrasting this to Michael Moores Roger & Me (1989), for instance.
