On review aggregator Rotten Tomatoes, of critics have given the film a positive review, with an average score of 7/10. The site's critical consensus reads, "Featuring visually striking CGI animation of its famed characters, Lupin III:The First is a charming and old-fashioned adventure romp."[72]
According to Pia movie ranking survey company from Japan, Lupin III: The First was ranked number one in movie satisfaction of all the releases on Friday, December 6 and Saturday, December 7, 2019.[73] Japanese reviews were positive toward the film.
A review at Gizmodo Japan says: "Toho keeps the animation quality high in this work as well, and is a perfect blend of the stylistic beauty of the Lupin series and the clear and accurate visual that is one of the greatest advantages of CG."[74] Cinematoday(ja) of Japan remarked the innovations from 2D animation adaptation is still present in this film: "In this work, the royal road style that incorporates elements such as bold actions, mystery solving, and the reversal that are the charm of the series is present. As for characters, while taking advantage of 3DCG such as three-dimensional action, the appeal of hand-drawn animation has been inherited for movement and facial expressions. As "THE FIRST", Lupin the 3rd: The First in its 3DCG animation commemorates the entry of a new era in the "Lupin" series."[36]
Shiraishi of Real Sound (ja) explains the 3D was "realistic" and the "animation stands out." The review explains the nostalgic themes present in the Lupin franchise such as "big jumps from roof to roof, the car chase in the familiar yellow car" all evoke the old Lupin despite the transition from 2D to 3D: "the Lupin gang remains the same." The review also noted its references to media and geography such as, "A careful copy of Paris in the first half of the 1960s, the remnants of the Nazi Germany."[33] Naoko Hosoda for Mantan reviewed the film has rare glimpses of Miyazaki's Lupin. The animation for the eyes were particularly noted for its clarity: "Lupin's eyes staring at Leticia are also gentle." In conclusion, the movie's action is at the scale of Hollywood by stating: "the action is truly 3DCG, and the speed and scale of the Hollywood movie are eye-catching."[75] The Japan Times stated, "A scene of Lupin and Laetitia sparring on a Parisian rooftop is so delightful, I wish it had gone on for longer; ditto a skydiving sequence that suggests the director has been cribbing from Kathryn Bigelow's '90s surfer caper, Point Break."[76]
Ungeek stated, "In fact, seeing the film feels like watching a movie-length classic Lupin III episode, in the best way possible!"[77]
Italian reviews marveled at the cinema whose franchise has been broadcast in Italy since 1979. Cinematik stated the movie's title The First is apt because of many reasons: "First, it is the first feature film made in CG; also it is the first film without the great master Monkey Punch. Finally, in this new adventure our Lupin III will try to get his hands on the Diary of Bresson, the only treasure that the famous grandfather Arsenio Lupin (I) never managed to steal. An adventure to which the famous thief has often accustomed us, made up of deceptions, breathtaking escapes, ancient mysteries to be solved, science fiction inventions, and secret organizations of the Nazi mold."[78] Madmass magazine with a four stars stated: "Lupin III - the First is technically superlative, an authentic enchantment for the eyes in which each sequence of frames appears a painting in bright colors. The emotional aspect is no less heart-pounding, spectacular and photorealistic action sequences, experienced both at full speed and in slow motion: in the middle of traffic, in the desert, or on board the yellow Fiat 500 of the Lupin gang."[79]
Marco Tedesco of Il.Cineocchio marveled at the limitless plots that can be created from the world stating, "Even in such an indistinct setting, however, it is capable of giving birth to stories that can push the viewer to doubt what is possible in this world."[80]
French review by Caroline at the Annecy International Animation Film Festival stated the charm of the characters is present because it is a right mixture of cartoonish and photorealistic characters: "Far from looking for hyper-realistic effects that would have made Lupin III and his band difficult to recognize, the animation has fun playing with the laws of physics and frees itself from the constraints of anatomy. We recognize him by his corner smile of course, but we find him especially in his fluid and elastic movements so characteristic, which are quite respected."[9] Tasha Robinson's review for Polygon found many parallels to The Castle of Cagliostro and believed, "But while the newest film in the series may never replace Castle of Cagliostro, they make a fine double feature."[22]
Matt Schley of IGN reviews stated "With the new visual style, the detailed textures of the film’s vehicles, clothing and other objects practically pop off the screen. Rather than total realism, Yamazaki seems to be aiming for something more cartoon-like, and some of the best shots almost look like fluid claymation. Lupin has always been about gravity-defying leaps and bounds, and this animation style fits perfectly. When jumping around the screen, Lupin’s body warps and stretches — not to the point where he loses all sense of weight, but just enough so he remains distinctly Lupin."[81]
Variety review by Maggie Lee highlighted the movie stayed to its roots: "Setting this film in the early ’60s not only plays to his strengths, but also preserves the ambience of the original in architectural, vehicular, and panoramic designs, emulating the intense and vibrant color schemes of post-war French-Belgian bandes dessinées." In terms of animation the review stated: "A grand entrance is staged in elegant, showstopping style, from chandelier gymnastics to a rooftop chase, all with breathless balletic grace that also reveals period Parisian cityscapes in romantic splendor." The final verdict was: "This lavish, technically polished animated caper featuring the beloved gentleman thief of Japanese manga delivers high-octane entertainment but plays safe with the canon."[30]
