good back-story, and good acting

A Masterpiece!

The film makes a home in your brain and the only cure is to see it again.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

A fast paced and enjoyable movie, not a classic but definitely funny and interesting

The other bad reviews here are not being overly critical or nit picky, this movie is really bad. Some points I'd like to make:Have you ever had the misfortune of spending time near someone with pink eye? It is uncomfortable, slightly disturbing, and some thing you will want to divert your attention from. So, why would a director give all the characters this effect?? It just deflated any 'horror' aspect and made me feel like I was in a free clinic.And yet, I sat through it, as in a waiting room. I had to see the train wreck.Aside from a matchbook understanding of Law, and an incredibly stupid clothes-on love making scene that rivals that of The Room, I did appreciate the name dropping of Motörhead, Anthrax (early), and D.R.I. even if those bands are not that great, and though it painfully illustrates the director or writer's age and mental fortitude.I suppose if one is optimistic, Mayhem could be considered "fun". It could be "fun" to visit a leper colony too, but I wouldn't advise it. There are so many well-crafted and interesting horror films to watch, I wouldn't waste my time with this one. It's just bad, like really bad, not even in an ironic or clever way.What was with his "best friend"? They seemed to have nothing in common, talk briefly about nothing, and then he's dead before we know anything about him, or the nature of his friendship to Derek. When his dead "best friend" gets pissed on, Derek cries- blaming the virus. Yet, he has the wherewithal and cognizance to scheme and fight his way through the building?The list goes on. Why did I watch it? I saw it as the image for the Shudder app on my FireTV, so I foolishly thought it might be worth a watch. I was wrong. Watch 'Train to Busan' instead.

A virus spreads through an office complex causing white collar workers to act out their worst impulses. Mayhem is like The Belko Experiment but even worse with an off balance between horror and comedy, terrible characters and over the top acting. This movie might find it's audience but for casual viewers and fans of genre is a skip. (0/10)

Joy Lynch, I like you dude. I really like you, I like the Movie Crypt podcast and I like that you are a huge, huge film fan. However, this movie is beneath you. You deserve better. Better scripts, better actors, bigger budgets. I don't blame you for the end result. You did what you could with the limited budget.At the end of the day, this movie was just a waste of time and talent. And this chick Samara Weaving. Ugh! I really can't decide whether it's her truly horrible acting or the way the chararcter was written, but it was extremely painful to watch her. There's really nothing more annoying than a chick who tries WAYYYYYYYYYYYYYY too hard to look and sound like a badass. Every time she was trying to be a badass it was cringe after cringe after cringe. She comes across as a cheap, forced, utterly cringy, B-movie version of Margot Robbie in Suicide Squad. She was extremely fake in her delivery of the "badass" lines and Joe's attempts to shoot her by using "cool", sexy angles didn't help. A real badass female character is Linda Hamilton in T2. Why? Because we have time to get to know her and the script doesn't force her "badassness" on the viewer. With a better actress and a better script, I'm sure Joe would've been able to create a REAL badass female hero. In the end I'll say this: even though I hated this movie, I still like Joe and I will continue to support him. And I'm sure that next time he will deliver an infinitely better movie.
