While filmed well enough and looking at least somewhat polished, there is one element that make Amelia's Children more unintentionally laughable than scary.... While there is great cinematography and some great effects, the main antagonist has this laughably gross look that detracts more than it gives, especially during some of the more significant scenes. The bits of blood are at least done well enough and there is some polish to how scenes look. Night scenes almost have that sense of terror, with some selectively great suspense-building shots and just enough lighting to see what's going on, except again the laughably comical looking antagonist.
Acting is more miss than hit. Performances across the board were wooden, with only a few moments of true acting range during heightened tensions. I wish there was more to say here..... The story is, likewise, barebones and all-too-familiar. Once the bits of backstory come about, you've already guessed most of it and the rest is far too easy to predict..... The soundtrack is a bit too repetitive as well, with far too many similar sounding compositions popping up. Sound effects are only around for specific bits and don't add anything to the scene either.
If you really, really, want to watch a movie with a laughably bad looking antagonist, then I guess Amelia's Children would be the one to watch. Otherwise there isn't much going for it, aside from some great visuals.
