[11] Adeayo Adebiyi of Pulse Nigeria noted that in The Guy, M.I Abaga aimed to showcase the personal side of the man behind the art, blending themes of love, gratitude, masculinity, and mental health, while balancing playful and serious subject matter.

[13] Emmanuel Daraloye, writing for Afrocritik praised M.I Abaga's The Guy as a diverse and emotionally rich album that explores themes like mental health, love, and success while reinforcing his legendary status, describing it as "something to dance to, meditate on," and rated it 8/10.

[14] Uzoma Ihejirika of The Native described M.I Abaga's The Guy as a reflection of his enduring legacy, with M.I blending decades of lyrical prowess and evolving with the times.

[15] Michael Aromolaran's review of The Guy for the Culture Custodian, he critiqued the rapper's tendency to rely on repetitive themes and weak lyrics, suggesting that at 40, M.I's artistry feels stale, with lines like "some of you no dey ever hear the message, and that's on Glo" lacking innovation.

Aromolaran noted, "If youth breeds ambition, middle age tames it," highlighting a shift in M.I's focus from bravado to more personal themes, ultimately finding the album to lack the energy and joy of his earlier work.
