He flew to Florida to work on the track titled "Ayo Technology" with Justin Timberlake, and the song was finished in Houston, Texas.

[9]Stylus Magazine's Jayson Greene writes that "the beats on Curtis sound about as dated and cheap as any Koch record", and that "each no-name producer (Veto and Roomio?

[10] Pitchfork Media's Ryan Dombal also comments that 50 Cent "should be able to work with producers who could conjure his hit-making abilities, but instead the MC mostly sticks with tried-and-failed G-Unit stalwarts and Dre-aping up-and-comers that do him few favors".

[11] Dave de Sylvia of Sputnikmusic writes of the production on "Ayo Technology", "Timbaland's shred-guitar-goes-keyboard melody is just mesmerising enough to work".

[12] RapReviews editor Arthur Gailes states that "there is no dip in quality lyrically; 50 is often criticized for not being a good lyricist, but he's exceptionally witty in his writtens", and adds that 50 Cent "manages to cover different themes very well", noting his "seduction" on "Follow My Lead".

[2] Greene writes that 50 Cent is trying to "revisit the raw fatalism that defined the best tracks on Get Rich or Die Tryin' ", quoting lyrics from "My Gun Go Off" as an example: "You know tomorrow's just a day away / If you can just keep your heart beatin' and your ass awake".

Club wrote that 50 Cent "has yet to master the art of making a satisfying album rather than delivering a random assortment of demographic-pandering tracks".

[22] Chicago Tribune critic Greg Kot wrote that "at a time when consumers are expressing their dissatisfaction with music-industry product", Curtis provides "exactly what they say they don't want: More of the same".

[23] Chase Hoffberger of The Austin Chronicle found 50 Cent "redundant" and said that the album "tires on second-rate beats, juvenile hooks, and rote lyrics about money and guns.

"[14] Slant Magazine called 50 Cent "one of the worst lyricists alive", criticizing "Amusement Park"'s lyrics and the execution of his metaphors which he "mumbles without a hint of irony or conviction".

[17] In a positive review, USA Today's Steve Jones wrote that its themes of "chip-stacking and sexual prowess [...] aren’t new", but stated that 50 Cent "delivers them with unmatched swagger and flair".

[25] Greg Tate of The Village Voice stated, "Curtis is stuffed with tightly wound 21st-century pop songwriting, full of that invisible craft and flow that renders a thing eminently listenable even if it's gratuitously raunchy, politically reprehensible, and sexually retrograde.

"[26] On his mixtape The Big 10 (2011), 50 made references to the mixed reception of Curtis on the opening song "Body On It": "If a n**** say I fell off all I want you to do is ask him when ?

[28][29] PopMatters editor Josh Timmermann cited "I Get Money" as "the collection's clear MVP, an iron-fisted ode to living large".

[35] It had the fourth highest sales week for an album in 2007[35] (topping Linkin Park's Minutes to Midnight which sold 625,000, then outsold by the Eagles' Long Road Out of Eden, which moved 711,000 units[36] and later Alicia Keys' As I Am bringing in 742,000 copies.

[37]) It also had the highest sales week for an album by an East Coast-based artist since Jay-Z's Kingdom Come debuted with 680,000 copies sold several months earlier.

[38] However, Curtis brought in the third-lowest first-week sales of 50 Cent's career, with Get Rich or Die Tryin' selling 872,000[39] and The Massacre moving 1.14 million copies.
