Meh..it was just ok. There was some good build up but NOTHING ended up happening. No alien crafts, no aliens, no intelligent life beyond Earth...NOTHING!
The film also suggested that "we are it." There is no intelligent life beyond Earth, which is something I completely disagree with. We need a new real movie about life outside of this Earth along the likes of Contact, Arrival, They Live, etc.
So despite Brad Pitt being a badass, it wasn't his best work imo.
