Im sure(if your as picky and observant as i am) you have heard this before when picking up flaws in movies.
Here are a few ive noticed:
Trains DO NOT stop, EVER. Even if your spotted they would rather hoot there horn before even attempting to stop.
Pistols make brilliant weapons, when there empty simply throw them at the enemy instead of keeping them and attempting to find more ammo.
The bad guys favourite(UZI or Mac10) has a never ending supply of bullets which you can out run as they land at your feet.
Glass is a very strong material , accept of course when you rope into it where it smashes letting you ,inside instead of bouncing off.
Nobody hears drills as they drill holes for mini cameras. Also, cameras are never seen to be poking through .
The 'good guys' always win.
Arrows can be pulled out straight away.
Explosions are meerly bright lights and burns never occur.
