IGN rated the pilot episode 8.4/10, praising the series' "casual take on zombies" and Rose McIver's performance as Liv. LaToya Ferguson of
The Onions
The A.V. Club graded the series an A− and stated the series is better for diverging from its comic-book origins. She praised the series for having the same quick-witted banter as
Veronica Mars, and observed it measures up well against
Pushing Daisies, noting: "Television can only be better for having the voices of Thomas and Ruggiero-Wright back on a weekly basis". Inkoo Kang of the
Dallas Observer called the series, "dazzlingly, tirelessly witty" with an "acute attention to human relationships", and praised it as "the summer's most underrated series". The second season was also met with positive reviews. It holds a 100% approval rating on Rotten Tomatoes, based on 14 reviews with an average score of 8.39/10. The website's consensus states: "
iZombie smoothly shifts gears in its second season, moving between comedy and dramatic procedural, while skillfully satirizing modern society along the way." The third season received further praise with a score of 100% on Rotten Tomatoes, based on 10 reviews with an average rating of 8.56/10. The website's consensus reads, "Broodier and brainier,
iZombies third season may be its best yet". The fourth season has been met with similar praise. It earned a score of 92% on Rotten Tomatoes, based on 12 reviews, with an average rating of 8.13/10. The website's consensus reads, "
iZombies fourth season boldly flips the board on the series narrative, injecting fresh blood into its amiable corpse and promising that it won't go stiff anytime soon". On
Rotten Tomatoes, season five has an approval rating of 71% based on reviews from seven critics. The series finale was met with notable negative response, however. In March 2022, nearly three years after its airing,
Paste reflected that both the finale and final season as a whole seemed to have suffered due to Rob Thomas' preoccupation with the concurrent revival of
Veronica Mars, and stated, "The finale of
iZombie was one of the worst TV-viewing experiences I have ever had. As the minutes unfolded, I became filled with horror watching everything fall apart. The characters I had loved for five seasons turned into strangers. And when the credits finally rolled, I found myself questioning all the love I had put into it." The same month, Rahul Kohli admitted dissatisfaction with the finale, saying that he felt that it "sucked" and was "super disappointing".
