Critical response Koi... Mil Gaya opened to a positive critical reception, with most critics applauding the cast's performances (especially that of Hrithik Roshan). Rekha and Zinta's performances were panned; several critics found them to be "utterly wasted" serving only as the film's "decorative piece[s]". In spite of that, Rekha's performance was better received critically. Udita Jhunjhunwala of
Mid-Day observed, "You walk into
Koi... Mil Gaya expecting to find a mysterious alien, what you end up discovering is a child inside you." She praised Roshan for his performance in "his bravest role". Bollywood Hungama noted, "Hrithik Roshan dominates the show and packs in a power-packed performance. The role of a mentally challenged person is no cakewalk, but the actor takes to it like a fish takes to water. He manages to pull off the zero-to-hero routine exceptionally well. As an actor, he scales dizzier heights with this splendid performance." Rediff.com's R. Swaminathan called the actor "the turbojet that propels the film to the realm of the extraordinary", and believed that the film's screenplay and dialogues gave his character "flesh and blood". However, he felt Jadoo's design was "a big letdown", saying that it was "plasticky" and "does not exude life". Writing for
The Afternoon Despatch & Courier,
Deepa Gahlot described
Koi... Mil Gaya as "a great demo of the Bollywood style of filmmaking", but criticised its scientific inaccuracy. Manjulaa S. Negi of the
Hindustan Times was not satisfied by the special effects and compared them to
Independence Day (1996).
Screen editor
Bhawana Somaaya appreciated Hrithik Roshan's performance, finding it to be "very sincere" and "brave"; she also took note of the film's "refreshing" subject. Sharing a similar view,
Dinesh Raheja felt Hrithik Roshan had delivered "a cherish-worthy performance". Both critics added the child actors, who accompanying Hrithik Roshan's character throughout the film, contributed positively to his performance.
Khalid Mohamed, who gave the film four stars, presumed that Rekha's role made her "restrained"—an opinion shared by Nahta. Of Zinta's performance, Nahta opined: "Preity Zinta does not have a very significant role in terms of the value she adds although she has a running role. She looks pretty and acts well." Chitra Mahesh from
The Hindu commended Hrithik Roshan and the cast of the children, while referring to the character Jadoo as "amateurish". In his five-star review published by
B4U, Parag Chandrabala Maniar lauded the efforts of Rakesh Roshan "to provide pure and clean entertainment" and Kolbe's and Mumma's special effects. He said of Hrithik Roshan, "[He] proves his versatility as an actor. At times he moves you and at others he makes you laugh. Here's is (
sic) definitely an actor to reckon with. The number of flops notwithstanding, Hrithik Roshan is here to stay." Meenakshi Rao of
The Pioneer complimented his acting style, considering him to be "endearing, as endearing as a child of his mental age".
The Times of India Omar Qureshi elaborated, "Hrithik blows away all doubts, theories, criticisms and disbelief with an extraordinarily touching performance of a mentally challenged boy in a rough man's world. He surprises you with his reserves of pathos, his gamut of emotion and his transition from weak boy to strong man. Here is a sterling act, worthy of all awards this year—thus far. He is simply incredible, even in his voice modulations, his sloppy walk and his lopsided smile." An
Indo-Asian News Service critic wrote that the pairing of Hrithik Roshan and Preity Zinta took "the couple conventions of Hindi cinema far beyond the escapades of typical Hindi cinema". Overseas critics focused their attention on Hrithik Roshan's performance and the film's themes, while also pointing out its many similarities to American SF films (most notably
E.T.). Ed Halter of
The Village Voice predicted that the film's elements, including its "nonstop plagiarism from classics like
E.T.,
Star Wars, and
Close Encounters of the Third Kind", might be embraced by foreign nerds.
Grady Hendrix of
Film Comment commented that the film was an "embarrassment of riches", summarising, "... it's mockable, it's silly, it's cloaked in a cloying miasma of cute, but its off-handed facility with pop-cinema conventions, spiced up with some jarring stylistic disconnects, delivers the most mind-bending entertainment experience of the season. This is commercial moviemaking taken to its logical, mondo mercantilist conclusion."
M. J. Simpson expressed approval of the entire cast, especially Hrithik Roshan, whom he regarded as the film's "oddest aspect". Calling it "bright, loud and relentless fun",
Jürgen Fauth gave the film three-and-a-half-out-of-five stars and reviewed its comedic, romantic, science-fictional, musical, action, and melodramatic elements positively.
Empire magazine hailed it as the "most novel Bollywood movie of the year". The
BBC's Manish Gajjar described Hrithik Roshan's role as a "mentally-retarded-child-[turned]-superman-hero".
Derek Elley praised him for avoiding his typecasting as a romantic hero, while David Parkinson of
Radio Times thought that the film served as "slick, sentimental entertainment". Writing for
TV Guide, Maitland McDonagh singled out Jadoo's expression in the scene where he is lost in a forest for praise.
