Club wrote that Junior Boys "hold to a style that's danceable but purposefully dry", adding that their "emphasis on the aloof and mechanical doesn't diminish their feeling for how humans relate to technology".

[8] Mark Pytlik of Pitchfork hailed it as "among the best records you'll hear all year", writing that in spite of Junior Boys' departure from the "rhythmic capriciousness" of their debut Last Exit in favor of more "comparatively streamlined song structures", the album "draws out so many of the same sensations and colors that it feels like a natural next step".

[13] Andy Kellman of AllMusic noted the prominence of "slowly unfurling material that projects a cool sense of comfort", as well as a "semi-subliminal undercurrent of self-deprecation that carries through most of the album" in its lyrics.

"[11] In a mixed review, Dom Passantino of The Guardian called So This Is Goodbye "pretty, if sterile", while nonetheless concluding that "despite their lack of heart, there's no reason Junior Boys shouldn't be able to survive.

"[10] Spin's Michaelangelo Matos was far more critical, writing that the album suffered from the absence of former member Johnny Dark's "rhythmic contributions" and, with the exception of "In the Morning", "turns the pathos of [Last Exit] into nearly intolerable bathos".
