The movie really took a long time to get going. I noticed both in this and in Dead Reckoning, there was a lot of wooden, stilted line readings. And I know the MCU was popular for a long time, but did we really need all those callbacks and tie ins to the previous films? I didn't need to know that the evil AI came from the rabbits foot from MI3. Not sure that really adds anything to either film.
I think my favorite scene in the whole movie is Ethan breaking into the downed sub from the opening of Dead Reckoning. It had that eerie haunted house atmosphere. And the propeller plane chase was straight out of an Indiana Jones movie.
Its weird how the plot is basically just Tom Cruise Prevents Judgement Day. The Entity was literally going full Skynet on the entire world.
