- Alas, Poor Scrappy: Laurel by this point honestly didn't even qualify as a full on scrappy anymore for a large part of the fanbase. However, she still wasn't exactly the most beloved character on the show, but she died without any of her family being present, and did make great strides in her vigilante work.
- Broken Base: The fan base is split between those who like that Laurel is gone so that there can be less focus on her and those who hate The CW for killing off the last character with a direct comic counterpart on Team Arrow (not to mention the comic wife of Green Arrow). This case of Franchise Original Sin has led a sizable amount of the fan base in the latter camp to quit the show altogether, along with the creation of the hashtag "#NoLaurelNoArrow". People in the second camp also point out that Laurel has been largerly Out of Focus compared to Oliver, Felicity, Diggle, and Thea, and that after reviving her sister she hardly took up any unnecessary screentime at all, and that it smacks heavily of Death of the Hypotenuse getting in the way of Olicity shipping.
- Franchise Original Sin: The episode is seen by many as the culmination of the show's on-going Seasonal Rot since Season 3 - killing off the only heroic character after Oliver who has a direct comics counterpart - Dinah Laurel Lance, the Black Canary. This is made worse by the fact that in most of comic canon, Dinah Laurel Lance and Oliver Queen are at least a couple, and in the pre-Flashpoint timeline, they were actually married, erasing the possibility of that portion of the comics being shown.
- Harsher in Hindsight: Back when Season 3 opened with killing off Sara, this drew a lot of ire in the fandom, with many claiming they had "killed the wrong sister". By this point Laurel had been Rescued from the Scrappy Heap for many, and the reaction against her death is perhaps even more vocal than the reactions to Sara's death.
- He Really Can Act: The male cast members gave a very strong performance in this episode, David Ramsey and Neal McDonough especially. Katie Cassidy also gets to show how far she's come since Season 1.
- He's Just Hiding!: Given that Laurel whispered something to Oliver before she succumbed to her wounds, theories that she's just Faking the Dead and Oliver is her Secret Keeper began to surface (Word of God denies it, though they lied before). Also adding fuel to the fire is that the show runners have openly admitted that they started making the season with no idea who was going to be in the grave, leaving the possibility that they could end up deciding it wasn't anyone. But then there's the major argument against this theory, that it would be unforgivably cruel for them to keep the secret from the rest of the team, especially Quentin.
- Moral Event Horizon: It's needless to say that Darhk and Merlyn crossed the line a long time ago, but Andy crosses it in this episode, as it is revealed that everything he did for Team Arrow was nothing but trickery in order to lay them down to Darhk's feet. In a meta-sense, Marc Guggenheim and Wendy Mericle crossed it by committing Franchise Original Sin. After two seasons of Seasonal Rot, this was the episode where fans REALLY turned on them.
- Overshadowed by Controversy: As detailed in Franchise Original Sin above, the outcome of the episode received huge backlash on from majority of the fans of the source material and even the comics writers, enough to take a toll in the show's ratings immediately after the following episode (which features laurel's funeral).
- Scapegoat Creators: Marc Guggenheim, Wendy Mericle and some of the writers know that both the comic fans and Laurel/Black Canary fans will want their heads on a silver platter after this episode. The first two claimed that they understand how those fans feel but they're not that bothered by the backlash. Unlike most examples of this trope, however, they did have a major hand in Laurel's death.
- Tear Jerker: Laurel's death.
- What an Idiot!: Laurel's death was ultimately preventable, if not for a few very stupid moves.
- Firstly, what exactly was Team Arrow's reason to rebuild to idol and keep it as a trophy? They inadvertently made things much easier for Darhk. Strangely enough, they kept one piece separate so that it couldn't be used, but then kept that same piece in Star City where it could be found (and evidently easily enough, given Andy didn't have trouble finding it). Given Vixen helped break it and their close ties with Team Flash, it wouldn't have been hard to give them the piece, or just keep multiple pieces hidden in different locations. Or, you know, not rebuilding it in the first place. You could argue they rebuilt it to have leverage over Dahrk should he break out, as no-one on the team believed Darkh would stay behind bars for long, but to completely rebuild it while only keeping one piece missing is blatantly stupid.
- Secondly, what was John thinking bringing Andy along in the first place? Even ignoring the possibility he was still under Darhk's influence, but he was, as far as John knew, injured and, if he was loyal, then he'd have a target on his back as soon as Darhk got ahold of him. Especially when Darhk takes him hostage to get the team to stand down; if Andy wasn't working for Darhk, than Darhk would have killed him anyway immediately after.
- By extension, Diggle's adamant refusal to believe Andy could be working for Darhk still. Given he was literally brainwashed and Darhk has magical abilities, even if he believes that Andy is good, he has to acknowledge that Darhk could still hold control over him. Hell, given Diggle is the poster boy for the 'don't have a blindspot for family' chant, him trusting Andy so much, given Andy has constantly let him down in the past, the fact he believed him over Oliver's logical reasoning is rather out of character. Even Oliver points out how irrational Diggle is, and literally spells out to Diggle that the latter advised him not to have blind spots.
- When the team rush Darhk and he takes Andy hostage, you'd have thought that Laurel might have remembered her Canary Cry, which would have allowed them to free Andy without surrendering, as well as thrown the prisoners off. This is particularly glaring since it got some upgrades last week that basically reminded viewers it was a thing.
- And lastly, when Oliver manages to gain enough freedom to fire an Arrow at Darhk, he of course picks one with a sharp head that Darhk could then easily use as a means to kill Laurel. Ignoring how stupid it is that Oliver, who's twice sworn to become a non-lethal vigilante, even has lethal arrowheads anymore rather than non-lethal trick-arrows or would use that instead of an explosive one, he knows that Darhk can magically catch arrows, so this tactic would be useless. You could justify Oliver having lethal arrows because: A) they live in a world of metahumans and sorcerers, so Oliver might find himself in a situation where he can't afford to hold back if he wants to live and B) Oliver is skilled enough to non-lethally dispatch criminals using otherwise lethal arrows. To use them against an opponent which has repeatedly proven immune to them, however, reeks of plot-enforced stupidity.
- The Woobie:
- The Lance family suffered yet another tragedy.
- Thea lost the closest thing she had for an older sister. And her biological father had a hand in it.
- Diggle completely loses his brother to the dark side, and his honorary/surrogate sister to death. What's even more sadder was the former had a hand with what happened to the latter, and Word of God says Diggle blames himself for it.
