A better way for the film to end...
Let me preface this by saying I absolutely loved this movie. It didn't take itself too seriously, perfect runtime, most of the side characters were surprisingly deep, and Samara Weaving absolutely killed it. That being said, I feel the very end could've been a little more thought put than just everyone exploding.
With all the accidents that got people killed and with the people Grace killed, I thought things would keep going that way until the whole family was wiped out by dawn therefore fulfilling the prophecy, but without some devine intervention.
