Hypebeast christened it "a fun and upbeat summer anthem," and Consequence of Sound dubbed it "a top-down, tunes-up party track.

"[43] Billboard called "Most Ain't Dennis" a "braggadocios track in which the artist flexes his accolades and how his counterparts pale in comparison.

[59][60] The cover art for the single was designed by Cudi and American visual artist Glassface, who also helped produce the music video for "Flex" which was ultimately shelved.

[61][62] On June 2, after premiering the lead single and hosting a listening session with fans in Los Angeles, Cudi revealed the album would be titled Insano.

The statues of Cudi stood at approximately 33 feet tall, with red-purple lights blaring out of his eyes and a small spotlight out of his mouth.

[87] Reviewing the album for PopMatters, Igor Bannikov stated that Cudi "does his usual cosmic, moonish, entergalactic stuff in a relaxed, low-key manner, not aiming to make something iconic".

[89] Robin Murray of Clash called the album a "lavish return" but felt that it "isn't perfect" and is "at times disjointed" with "a few tracks here that could have been excised without disrupting Kid Cudi's central narrative.

[85] Pitchfork's Dylan Green opined, "To its credit, Insano is trying to do something different—that different thing, however, is just having DJ Drama provide thin narrative window dressing to a spate of uninspired Kid Cudi songs".
