<P> Andrea Towers of Entertainment Weekly gave it a positive review: "Ah, siblinghood . It's a complicated thing under the best of circumstances, but when motherly abandonment is at hand, well, the emotional impact is everlasting . Such is the case for sisters Regina and Zelena and twin brothers David and James, each of whom grew up in highly unequal circumstances and have been at odds with one another ever since," then later adds "While the sisters are ready to start over on newly feel - good footing, not every sibling reunion is a happy one tonight ." </P> <P> In a review from Rickey.org, Nick Roman said, "Ultimately, I think Once Upon a Time has been doing a great job of telling character - driven stories this season, more so since the return from hiatus . "Sisters" is a surprisingly emotional episode that manages to bring character journeys full circle in poignant fashion . And I think these sorts of stories will make the final stretch of episodes towards the end of the season all the more resonant ." </P> <P> Amy Ratcliffe of IGN said of the episode, "With the Cora angle played out and worn thin, the success of this episode rested on the bond between Zelena and Regina . Their interactions weren't anything earthshaking, but it was sweet to watch them find some common ground and gain new understandings of each other thanks to restored memories . Their forgiveness and tolerance of Cora was far too kind though ." Ratcliffe gave the episode a 7.5 rating out of 10 . </P> <P> Christine Orlando of TV Fanatic gave the episode a 3.9 out of 5 . </P>
