I feel like every aspiring parent should watch this. Not because it will dissuade them from having children, although it very well could, but rather the reason being that it shows how talking to kids about the serious events in life can be better than just leaving them in the dark on that kind of stuff. The premise of Goodnight Mommy is pretty simple. Following some undisclosed accident the mother of two boys returns home with a fully bandaged face looking all creepy and exhibiting strange behavior. This causes the twins to question if the woman is who she says she is. This whole thing didn't really click with me until the big reveal. The take away was great, but due to how heavily everything hangs on the mystery of whether or not the brothers are right it's hard to get too much out of the movie up until that point, even when things start to get disturbingly violent. The twist itself may come off as stupidly obvious to some, but it caught me totally off guard as a result of what a fine job the writers did at providing enough misdirection to keep me constantly guessing. Given how critical the ultimate eureka moment was to my overall enjoyment of the film, I question if it would hold up on subsequent viewings. I feel like going back into it already knowing what's going on would make for quite a frustrating watch, as the concept already requires a fair bit of suspension of disbelief even before you realize what a big, stupid idiot the woman with the suspect identity is. Of course, that frustration is likely to only help hammer home the message at the core of the experience. That being if you find yourself as a caretaker for children, biological or otherwise, having a conversation with them when life gets messy can potentially save you a lot of trouble at some point. So perhaps sitting through Goodnight Mommy more than once is really the best way to fully appreciate it after all.
