Although the cast is fun, and the pacing is good, the actual plot points and coherency are well past the point of believability. They are too numerous to count, but suffice to say the good guys had a number of obvious solutions that could have stopped the catastrophe. To add insult to injury, the movie overstretches its AI angle – had it stopped earlier, it would have worked within the narrative, but instead, they go for the sappy “teach me all of humanity” angle.
