My review (cross-posted):
With this episode, the people behind Arrow have officially created one of the best examples of how to handle death and grief on an 'action drama' since Joss Whedon did it twice with "The Body" and "The Gift" during the 5th season of Buffy the Vampire Slayer, taking the pathos of the former and fusing it with the frenetic action of the latter to create a phenomenal package that is far and away the best episode this series has produced to date.
From the official opening scene of the episode - where we see Sara's death again - to the last shot of Thea Queen-Merlyn training, the writers of tonight's episode were firing on all cylinders, giving practically every single one of the major characters something meaningful to do and showing just how deeply Sara was connected to most of them. We also got some nice developments for Oliver, Laurel, and Felicity that not only followed up on their individual stories from "The Calm", but also set the table for future storylines.
Laurel's reaction to her sister's senseless death really helped put her on the path towards eventually taking up Sara's legacy as the (Black) Canary, and also helped teach her the lesson that acting out of rage is always going to lead to problems even if you think it'll help. The only thing I didn't like about her involvement in this episode is that she chickened out of telling her dad about Sara's death. That's only going to lead to (unnecessary) angst, and I'm not sure that's an angle they need to be taking. I did like the montage bit of her at the end of the episode holding that stuffed shark and then lifting up Sara's black leather jacket, especially because the latter action serves as a nice piece of foreshadowing for where her story is eventually going to be heading.
Felicity and Oliver had some nice moments in this episode, with Felicity really earning her archetypal status as Oliver's "female confidante", what with her taking Oliver to task for seemingly being all stoic and hard when she felt that the best - and most appropriate - response to Sara's murder was to grieve. I also like that her reaction to Oliver's declaration that he can't let himself grieve was to move on and accept Ray Palmer's job offer, although I'm not sure it's going to turn out well in the end for either her, Ray, or Oliver.
I really liked Komodo as an 'antagonist of the week', and would like to see more of him. His fights with Oliver were really well-choreographed, particularly the motorcycle 'joust'. I would've liked to have found out who hired him, but sometimes a little bit of mystery is good.
I spent most of the episode wondering how John Barroman's Malcolm Merlyn was going to make his presence known, and the final scene was a great (re)introduction for both him and Willa Holland's Thea, particularly since it opens a lot of different story possibilities since she seems to have fully embraced her relationship with him, something that you can bet he's going to take full advantage of.
When I found out that Colin Donnell was going to be showing up in a flashback to Oliver's time in Hong Kong, I found myself more than a bit concerned as to how they were going to make it work without irreparably compromising the integrity of previous events, and I'm happy to say that they handled that particular subplot perfectly, with Oliver demonstrating some of the subterfuge and misdirection tactics that he used to great effect during Season 1.
Even if the producers hadn't said that Sara's death was going to serve as a catalyst for Diggle rejoining Team Arrow, it's something that that seems like it would've been inevitable just because Diggle really isn't the kind of character who could remain on the sidelines for very long even if he and Oliver both thought it was prudent for him to do so.
It was a really nice gesture of Diggle to tell Laurel that he and Lyla were naming their daughter after Sara, and that scene of him watching her in her crib added even more poignancy to what was already a really poignant episode, so kudos to the writers for that.
I liked that Roy was worried that Oliver was going to be pissed off at him for not sharing the note he had from Thea, and it was a nice bit of characterization for Oliver that his only response was a muted 'Okay'. I'm really interested in seeing what Oliver (and possibly Roy) is going to do when he finds Thea next week), and whether or not it'll come out what she's really doing.
Sara's funeral scene was one of the most moving things I've seen on TV in a long while, and was perfectly handled. I do kind of wish we'd seen Diggle, Roy, and Laurel follow Felicity and Oliver's lead in tossing dirt onto her re-opened grave, but it was probably 'too much' for them to process.
I'm giving this thing an enthusiastic 10 out of 10, and can't wait to see what the fallout from tonight's events is going to be both in next week's episode and in weeks to come.
