The first episode of Arrow's fourth season ended with a funeral. The second finished with a grave being dug up. In Restoration, the third episode, we have someone being brought back from the dead. As spoiled by the fact that Caity Lotz was already confirmed for spin-off Legends of Tomorrow, Sara Lance was revived thanks to the Lazarus Pit, although she hasn't exactly came back the same. Aside from that, we also had the restoration of Oliver and Diggle's friendship, another villain-of-the-week, a further glimpse of Damien Darhk's powers, and a lot of setup for the coming weeks. The other restoration was faith in this show's ability to be rather ridiculous, and yet somehow make sense and be utterly brilliant, because that's exactly what this episode is. It's fun, it's silly, it's awesome. It's still early in the season, but it's already shaping up to be much better than Season 3, even if some things did leave us scratching our heads for another week.
Honourable Mention: Can We Have More OG Team Arrow?
Arrow hasn't shied away from including moments that are purely designed to please the most rabid section of its fanbase - the 'Olicity' fakeout in Season 2, the boxing glove arrow last year - and a large part of this episode felt like pure fan-service. This was, of course, the reunion of sorts for the original Team Arrow, the OGs as Felicity refers to them. It's something myself and many other fans have wanted more of for quite some time now, and it didn't disappoint here, providing some of the highlights of the season so far (Felicity giving both of them a dressing down one notable example). These three have a lot of history and vast amounts of chemistry, and while it's good for the show to expand, can we please have more moments like this in the future?
