I thought the movie was so-so. The handgun volley toward the end was just plain stupid! (Yes, I'm doing people a favor for not putting spoiler tags on that)
I was also thinking that ironically, maybe it is "we" that have become too old to watch the kinds of movies that Sly and Schwarzenegger have been making? The plot vehicles and twists are too amateurish so it can never rise to being a serious action movie effort. If we viewed them through the eyes and experiences of, say, a 15 yr old, maybe we would think these are really cool movies (a lot more stuff would pass the sniff test, and the movie would come out with higher response)...but then the caveat is, no 15 yr old in modern day is rushing out to see geriatric Stallone or Schwarzenegger. So the optimal audience base for these movies is a bit of a paradox.
Margot Robbie is THE most exquisite human creature on the face of the planet, in this moment in time.
