At face value this is just another John Wick knock-off, or another disposable shoot 'em up like SHOOT EM UP, or SHOOTING ACES. It serves fans of action films well and owes a debt to '90s bulletfests out of Hong Kong too by John Woo and Ringo Lam et al. Gunpowder Milkshake has a bit more charm than your average hitman/woman film though and add to this some interesting set-pieces and heaps of humorous, gory scenes, Gunpowder Milkshake is a cut above the competition. Plus its not a sequel / remake / reboot which has to go in its favour, right?
