This is realistic compared to
Where Eagles Dare
in which thousands of rounds are fired inside a stone castle without ricochets, lots of Nazis die and Richard Burton receives a slight injury to the hand.

I can't believe how many people complain about this movie.

He finally gets tagged in the end. If you want an explanation it's simply the parallel Universe where he lucks out. That is the version we're presented with by the Multiverse God. In another Universe he gets taken out when his jet to Paris has engine trouble, and crashes in the Atlantic. In our Universe he's an actor named Liam Neeson who plays his parallel Universe self named Bryan Mills.

What in the hell is a "bombfire"?

I would like to know his name too. Sound like your BF can destroy any boxing champions or MMA champions. Using nunchucks and sword and do back flips at a same time, taking out 10 huge guys without scratch. Is your BF a super saiyan?

Oh, really? What's his name? Is he workin' on any big movies right now?
Let a little insanity into your life.

There are serious guys with serous skills. For example my BF in high school was a marital artist black belt & weapons master. He could use nunchucks & a sword simultaneously doing back flips and stuff.
I have seen him in a matter of minutes take out 10 big guys who were ganging up on a friend of ours by pushing him into a bombfire at the beach. And he finished without a scratch on himself. It was Fing amazing to see him in action. He now is a choreographer for movie fight scenes.
End of line.

I disagree

he's got skills.
The best lack all conviction, while the worst are full of passionate intensity.

You need to watch the movie again, Bryan misses quite a few times.
And then of course there's different types of firearm experience, there's professional (Bryan and some of the guys on the boat) and beep (everyone else) distance from gun barrel to the person you're shooting at doesn't matter if you're a crap shot.

You ever see 'Gangta lowlifes' on Crime dramas or those half assed militias from Sierra Leone/Liberia & see how they handle their weapons? They probably 'spray & pray' by holding their guns sideways over their heads because it looks "cool". Not surprising that Mills plowed through them like s**t through a goose. The guys on the boat were the only ones who seemed to have any sort of professional training.

its actually not that unrealistic when you look at the fact that most people out there who are trained shooters are in fact horrible shooters.
its obvious why all the bad guys are horrible
when it comes to someone trained by the CIA he/she would be a top notch shot

Yep - the "bad" guys are always terrible shots while the "good" guy can shoot a fly from a mile away. Quite unrealistic but hey, Hollywood has done it with a million movies.

Yeah the hero usually gets beaten pretty badly during the boss battle at the end of the movie

By the time he gets his daughter back he is limping pretty fiercely, has a gunshot wound to the abdomen, and a pretty deep gash on his arm. He's pretty beep up.

He's a badass
