Arrival:
The Redbox reviews fell into two categories - "Slow/Horrible" and "Reviews by People Who Are Not Stupid".
First off: Helicopters - check. Explosions - Check. So it's got two free stars right there (as we all know, the awesomeness of a movie is directly correlated to the number of helicopters and explosions in it), Cool aliens - Check, so there's three points right up front.
I found it to be a very cerebral and thought provoking movie. Definitely had to replay the dialog, which is sometimes lost in background noise. I found myself 30 minutes later going, "Wait, don't you remember when she said (blahblah), and then later, TOTAL (BLAHBLAH)!!" Whoa, mind blown! Language and math are two proofs of the divine nature of the universe in my book.
Don't want to over-hype it, but as an engineer, I enjoyed it. I give it over 5 stars, but then subtract a fractional portion of a star because Amy Adams nose is hyuuuge and they keep showing it in profile with the setting sun, and let me tell you that proboscis could defeat any global threat, so why worry?
Good movie.
