The critical consensus states: "What Wynonna Earp lacks in originality it more than makes up for in gritty, silly, supernatural fun.

The critical consensus states: "Wynonna Earp ups the ante with more action, more surprises, and more Melanie Scrofano as the titular sharp-tongued gunslinger.

[96] In its new series review, Collider gave Wynonna Earp four stars, calling it "a fresh and familiar take on zombies, the Wild West, and gunslinger culture" and "something that also feels different to anything we're seeing on TV currently, thanks not only to its setting, but its prominent placement of so many strong, profane, kickass female characters.

Club called Melanie Scrofano "the right woman for the job ... an easy, authoritative presence"; and "when it's allowed the room to run, Wynonna Earp delights in itself," adding that the series "could grow into the good-time Western pulp it has the potential to be.

"[150] In a post-season 1 review for Salon, Melanie McFarland wrote: "This modern Western proved its mettle by dint of unexpectedly weird plotting and witty dialogue ... [Melanie] Scrofano lends a hardened and slightly feral swagger to Wynonna that's vastly entertaining ... Much of the show's winning spirit rests in its exploration of family loyalty and the popular conviction that one's blood and dynastic ties compel one to fulfill a prescribed destiny.

[25] It was chosen by Variety as one of the 20 best new series of 2016, stating "what this prairie-set Canadian import lacks in budget, it makes up for in gumption, sass and camaraderie.

[28] The New York Times recommended Wynonna Earp as one of the television series to stream on Netflix, describing it as "internal mythology [that] can be a little too involved, but the characters' motivations are always clear, and the snarky dialogue is fun".

[152] "Wayhaught", the portmanteau for the relationship between Waverly Earp and Nicole Haught, was considered one of the favorite 2017 fan "ships" on Tumblr, and the series was praised for how it is portrayed and acknowledged by Dominique Provost-Chalkley and Katherine Barrell.

In the Season 1 finale, the harmful "Bury Your Gays" trope was challenged when Nicole survives being shot due to wearing a bulletproof vest.

[156] According to Kat Jetson of The Hollywood Reporter, Wynonna Earp deals with many feminist themes throughout the series and highlights strong female characters who are not defined by their relationship to men.
