The ending of 
MAMA always leaves me teary-eyed, many people were disappointed with the movie but i really like it 
 
and about 
Knock Knock for me was not a a psychological thriller or a scary/horror movie
For me it was a comedy a very dark one but still a comedy, so many scenes were 
hilarious 

 and i only watched it because of Keanu, i'm not a big fan of Eli
Ana de Armas (the blond one) is stunning and i think she kinda overshadowed Eli's wife
