This is a rare lo-fi horror film with an interesting lead character and a compelling script. Peggy really grabs hold of the narrative and drags it forward, kicking and screaming, as she encounters a host of memorable skeevballs.
The supporting performances - from the characters we delight in seeing get theirs to Peggy's more wholesome allies - are believable and energetic across the board. The setting also oozes small-town Midwestern-ness in every scene, giving the tone a unique flavor.
I was reminded of classic black comedies like Kind Hearts and Coronets (1949) and Heathers (1988), which is good, if nasty, company in which to find one's movie.
Overall, I'd recommend Peggy on the strength of its wild and chaotic kill scenes, true-indie cred, and surprising amount of heart.
