[8] Maggie Lee from Variety praised the film and described it as "While the action design and visual effects don’t compare to Hollywood superhero movies, they are solid by local standards.

Meanwhile, in a country with the world’s highest elderly population, the action movie’s anti-ageist thrust — demonstrating how undervalued senior citizens kick ass — proves unexpectedly heart-warming".

[9] Mark Schilling from The Japan Times praised the film and gave it 3 out of 5 stars, and described it as "The schoolboy and the salaryman will battle on in two sequels, both already set for future release.

[10] Manfred Selzer from Asian Movie Web also praised it and gave it a 6 out of 8, and describes it as "Eventually, there is a big showdown, and it is truly a lot more spectacular than we would have expected.

While we were already amazed by the special effects at the beginning, they become a lot more bombastic towards the end, even if you can't expect the level of a Marvel-movie here.
