Behind the glamor of effects and chases, the movie suffered from numerous goofs. So, the result was a disappointment. Here are 3 out of numerous examples of goofs and erros. 1) At some point the small VW Beetle car tumbled and when the car landed, Ethan and Grace inadvertently switched seats. That is physically impossible, considering the small size of the car and the impossibility for them to float up, while the car was trumbling, then land in each other's seats, come on! 2) The high-speed steam train cannot continue traveling for long, after Gabriel killed the controller who was supposed to continuously provide the steamer with coal or diesel and that is how steam trains operate. 3) When Ethan and Gabriel were fighting on the top of the train, with Gabriel facing the direction of train movement, Gabriel laid down to avoid being struck by the fast-approaching bridge edge. Then Ethan turned his head to realize the same thing and then also laid down. There should not be enough time for Ethan to look behind and then lay down, he would have already been struck by the bridge edge. Ethan should have followed Gabriel and laid down immediately without wasting time to look behind and then lay down.
