XFACTOR, Interesting that you enjoyed THE ARRIVAL, I seem to be the only person I know who didn't like it too very much for the following reasons ....
The extraterrestrials looked like Octopusses.
I sort of lost interest mid way through so I have no idea of the following .....
Was it explained how they ended up communicating? How was that accomplished? What were they here for? Why did they leave? Etc., Etc.
Saw it with family members in the biz who also though that it was a great film but somehow it went right over my head,
What was the message?
