Dan (Bill Corkum who also co-wrote this along with Steeves and Sutherland) and his heavily pregnant wife Neila (Holly Stevens) have gone to live in the countryside until the baby is born, on the advice of Neila's doctor (Sharleen Kalayil). Before too long they find their house surrounded by alien creatures and so along with local oddball Scagnetti (Mark Palermo) must try and survive the siege until help arrives.
I found everything about Aliens with Knives to be low key. It was low on thrills, low on character development for the most part, and low on plot but rather than take this as a complaint it actually made this really easy to watch. The violence was kept to a minimum, there's no swearing, and there isn't really any horror to speak off but made this quite peaceful to have on. Aside from the many aliens there are only a handful of characters the best three being Neila, Dan and Scagnetti. The couple never seemed to have any chemistry between them, this seemed purposeful as many scenes are set up to show their division and does set up later plot twists. Both actors in the couple are great at delivering their stupid lines with the straightest of faces. Palermo is also great as the local oddball, he had such a weird role, helped by the facial expressions and mannerisms he brought to it.
