A solution to the problem of an annoying friend is to "Just kill him." No worries, then.
My favourite part of this was the POV shots in Bunnings and the putting together of the murder kit. I could have just about watched the entire film from that perspective as it reminded me of Gorillas Film "The Package" a few years back. Equal favourite though was the excellent match cut you pulled off - so good! Good humour too with the mask selection scene. So, a lot of strengths but what we probably needed was to find out more about the characters and why the victim, in particular, was so despised. The murder/fight scenes needed richer sound FX too to really sell it to the audience. I wanted to wince and really feel those axe strikes.
I think this team is nearly there so one to watch next year.
