Like _The Belko Experiment_ before it, _Mayhem_ is a cathartic office massacre movie that's mean-spirited in a good way. _Mayhem_ however, has one thing _The Belko Experiment_ didn't: Fellow Australian Samara Weaving lowering the quality of the whole thing. _Final rating:★★½ - Had a lot that appealed to me, didn’t quite work as a whole._

79/100 A virus, which causes everyone to lose their inhibitions, attacks a prominent law firm. For the next 8 hours, no one is responsible for their actions. This exquisitely well-written, ultra-violent comedy had me thoroughly entertained from start to finish with some grossly genuine laugh-out-loud moments. Practically every scene had a visual gag or a quotable line that was precisely presented without it ever being forced on the viewer making the whole thing an absolute riot. If you enjoy films like "Evil Dead II", "Mom and Dad", and "Deathgasm", you'll love this one. -- DrNostromo.com
