Did you know the dad was really the ogre in disguise?
At the end of the movie, when the dad showed up at the house, did you suspect it was the ogre in disguise? Or were you genuinely surprised when the kid stabbed his own "dad"?
I feel like that scene is pretty ambiguous at first because the audience isn't 100% sure the "dad" is a fake or not, especially because we don't see him in the movie prior. Also, that kid seemed way too eager to stab someone who looked like his own father (even though the kid knew it was a fake), lol.
Especially right after the "dad" said I love you, and the kid was like "wrong answer" and flat out stabs him in the gut.
Earlier in the movie, the kid said he hated his mom and didn't want to live with her, but he probably has some very strong feelings about his dad too.
