Great acting by dogs
As revealed in the trivia-section here on imdb the dog was played by three different dogs. And they all had a great role. Actually the best role because the rest of the cast and writing in this piece of *beep* you call a movie sucked ass.
I actually warn my friends not to watch this film because it's literally a waste of time to do so. I watch a lot of horror and have seen really bad ones.. But Don't Breathe is actually bad enough to warn your friends not to watch.
The acting was horrible, the writing and logic was really weird and unnatural. The storyline felt just stupid (how hard is it for 2-(3) grown adults to kill a blind man.. Really?!)
And the few scenes that got tense and exciting the filming was so dark so you had no idea what was going on anyway.
I'm sorry but apart from the cool dogs this is by far the worst movies i've seen this year
