Critic Reviews for What We Leave Behind

What makes "What We Leave Behind" such an affecting episode is that all of those things are horribly, painfully believable, and have been building for a long time.

I'm very happy this was yet another installment featuring very little of the new characters.

What We Leave Behind is not a bad episode. In fact, it could even be said it's Arrow's best episode this year, not that that's a ringing endorsement.

Aug 2, 2018 | Rating: 2.5/5 | Full Review…

Although this episode slowed way down when it came to the comic book crossovers, it was the biggest stage-setting episode of the entire season, laying more plot groundwork than its predecessors combined.

What We Leave Behind strikes a careful balance.

What We Leave Behind might be the new benchmark for the series and further makes the case that Season 5 could be Arrow's best season yet.
