Whatcha Think About That

The Times music reviewer Elan Priya noted that "Whatcha Think About That" is an exception in an album that "lacks any distinct personality" and highlighted Missy Elliot's rap.[14] Alex Fletcher of Digital Spy gave the song three out five stars describing the song as "vibrant" adding "[the song] finds the pop troupe somewhere near the top of their game".[6] Samesame.com.au called the song "sensational".[11] Vicki Lutas from BBC Radio 1 praised Missy Elliott's contribution to the song, complimenting the introduction. "Of course, the song's greatness isn't all down to Missy Elliott alone – the Dolls certainly give it life – but it's safe to say that she does make this song just that little bit more distinctive"[10] Allison Stewart of The Washington Post wondered if it is the least objectionable song the group has ever done and described it as a "nifty tale of sexual role reversal."[15]

However, Nic Oliver in a review of Doll Domination from MusicOMH wrote, identikit urban beats, sleepwalking guest parts from Snoop Dogg and Missy Elliott, and lyrics that might as well have been written by a sophomore student on a weekend bender for all the depth on offer.[16] A critic from entertainment.ie echoed Oliver's comments writing, " [they] lower[ed] themselves to new levels of cheese with their contributions.[17] In earlier review from Digital Spy, Nick Levine wrote that, "[its] slightly disappointing after the hyperactive pop brilliance of 'When I Grow Up'".[5] Spence D. of IGN agreed writing, "the cool electro shock ambiance and unloads a much more straight forward pop angle that's missing some of the futuro risqué elements that made the two prior songs ['When I Grow Up and 'Bottle Pop') so catchy."[18] Slant Magazine music reviewer Sal Cinquemani did not favored the song calling it a "pure filler" despite the presence of Missy Elliott.[9]

The video starts with Missy Elliott singing her lines, and then switches to each of the Dolls singing a line of the song: Kimberly Wyatt, flexing her leg, then on a swing, Jessica Sutta popping gum; Thornton brushing her hair and Roberts puffing powder in her chest. The video centers on two plots: one shows the Dolls dressing for, and then actually performing, one of their famous Lounge Shows, clad in the exotic burlesque outfits for which they are known. After their introduction on the swing, the video cuts to scenes from the other storyline, where Scherzinger leaves behind her controlling partner, and goes out to have fun. She is shown turning a large key into a neon door, and steps out into the town, where she is joined by the other Dolls, and they walk the runway while singing the song's chorus. Returning to the other plot, the five girls are shown in lingerie in their dressing room, and the camera switches to Scherzinger as she sings the verse, and the other Dolls as they dress and apply make up. The remainder of the video focuses on the PCD burlesque show. The girls are shown on a rotating platform, then on a horizontal bar dancing and singing seductively in their vintage corsets and burlesque outfits. The scene changes, showing Elliott performing her rap, while the Dolls, dressed in seductive military outfits, perform a sexy army dance, accentuated by salutes and military steps. At the climax, the Dolls appear dressed in modern burlesque outfits, dancing intricately on a stage and Thornton singing the ad-libs. The video ends with Elliott performing her last lines, surrounded by the girls. This is also crosscut with scenes showing the silhouette of the Dolls as they continue to dance. Finally, the girls are again shown on swings, with Scherzinger singing the song's last lines.

A reviewer from Rap-Up wrote that "The Pussycat Dolls turn up the heat in their smolderin’ burlesque-inspired clip."[26] MTV News compared the music video of "Whatcha Think About That" to Danity Kane's "Bad Girls", concluding: "We like the Dolls' video better, but prefer the vocal stylings of [Danity Kane] for the simple reason that their song sounds less like a lesson in robotics and more like actual singing."[27]
