Makes sense. Kindergarten Cop was one of the pinnacle moments of cinematic history, there are references to it in many other games.
For instance, detective John Kimble trying desperately to maintain composer while being attacked by half a dozen small children is replicated almost verbatim in God of War 3, with Kratos getting piled on by enemies in God of War 3.
Kimble has to break free of his stoic persona and accept the love of the children in order to grow as a character. Kratos must break free of his enemies to slaughter them in revenge for his own dead child, and become more powerful in doing so.
Plain as day.
