The website's consensus reads: "Though the narrative remains too ambitious, DC's Legends of Tomorrow enjoys a freer creative arc with the removal of problem characters".

He noted while the season is "crammed full of compelling character arcs and plot twists", it thrived simply by "offering a sense of whimsical adventure and comedy that be frustratingly hard to find in other live-action DC projects".

[86] Caitlin Kelly of Hypable wrote Season 2 works so well because of its new roster, the evolving dynamics of its main characters, great villains, and the fun, which made it easier to not care about plot holes.

[87] Several years later, Matthew Sonnack of CBR called Season 2 the best of Legends of Tomorrow, "with the perfect balance of action, humor, drama, and heart".
