Saw it today. Read the book quite a while ago. Unfortunately I had to take a 20 minute call with my lawyer that covered the first contact part.
Pretty decent translation of book to screen. Had to suspend a bit of disbelief in places such as the size of the ship.
I didn’t get the Rocky homage to “Adrian” until this thread, so thanks for the enlightenment.
Shout out that, for once, the Chinese line spoken by the German Hail Mary lead actually convincingly sounded like a German person that could speak Mandarin. The line was "无所谓.“ Pet peeve of mine is that almost every freaking movie out there that has the non-Chinese actor saying one or two lines of unintelligible purported Mandarin would be better served being dubbed. Dubbing is pretty good now, and having Tom Cruise or whomever utter “arghugrhaha” as Chinese takes me out of the scene every time.
