Really? (spoilers)
Don't get me wrong, the movie was good enough, but that ending... Really? They all walk off into the sunset together? All three of them?! Seriously anti-climactic. It felt like two siblings getting caught after they did something bad and their dad was like, "I don't know what you kids have been up to, but no more. Got it? Now lets go for a walk in the park."
So weird. Not even a shred of anger on his part. He was just like... "Wow. My wife is having sex with her brother. Better see if I can get her to stop." Who shrugs that sh*t off? He didn't seem mortified at all!
