Ice breaking scene right out of DAMIEN - OMEN 2...oh wait, the whole film is...
*** POSSIBLE SPOILERS AHEAD***
Seriously, I literally heard Jerry Goldsmith's devilish THE OMEN music in my head when I saw THE GOOD SON, especially during the pond scene, which is very similar to the one in DAMIEN (1978).
And while we're at it, DAMIEN is also about two boys (slightly older, but not much), of course one of them being the Antichrist, and it doesn't end well for one of them, either....
Oh, and did I mention that both characters are called Mark...?
Maybe Henry's mom should have examined his hair when he was sound asleep one night to look for a strange numbers tattoo... :-)
