In 2010, Patrick Boivin had a viral hit with Iron Baby—an expensive-looking, CGI-heavy home video featuring his daughter in an Iron Man costume. The video received 13 million hits and is commonly regarded as a classic of the “cute baby in a superhero costume” subgenre.

Two years later, Boivin is back with Dragon Baby, another expensive-looking, CGI-heavy home video—this time featuring his son in a Kill Bill costume. It’s only been online for three days, and already it has 4 million hits. Along with The Godfather Part II and The Dark Knight, it is one of the rare instances of a sequel that surpasses the original.
