Very believable but far too slow

Rating: 8/10 (23 July 2019)

Really good sci-fi movie in the same class as 2001, Contact and similar.
Plusses - authentic take on what is probably required to communicate with aliens, realistic military knucklehead paranoid reaction, great CGI, realistic believable (non-human) aliens, good acting
Minuses - far far too slow, depressing dark dull monochromatic colours, some really annoying characters almost as bad as Prometheus but not quite that bad, really annoying flash forward scenes that honestly don't add that much to the story, slow pace of story progress, dumb authority response
Overall a good movie, well worth watching, gets you thinking, but you might not want to watch a sequel if it was directed and produced the same way.
