100lb Woman Beats Up 300lb Man? Really?

So anyone who sat through the flick and happened to pay attention to the sloppily edited train brawl, did the filmmakers get so lazy as to think that people wouldn't completely roll their eyes seeing someone as tiny as Noomi Rapace disarming and headbutting that huge 300lbs dude?

After he smacked her around a bit it was just kind of silly that she was able to fight him off until Leo came to her aid. This movie had some fairly dumb moments, but I nearly eye-rolled so hard at that sequence if I had been in a plane at the time it may have started a twister in the clouds.
