Michèle at the gun range

This was odd. Of all the things in this movie that one might find not ringing true, the one that stuck out to me was the scene where her employee takes her to a gun range to learn to shoot. Other than the ridiculous site of Isabelle (who may be 95 lbs soaking wet) with the giant Dirty Harry Callahan .44 and handling it okay, she turns to the side and is holding it pointing right at the other guy's torso. This is exactly the kind of thing a newbie on a range like her would do, but he's presumably experienced using firearms as he owns a few and is teaching her. He has no reaction this? Anyone who has gone to a range with someone new knows that's the kind of thing they will do without thinking, and you have to watch out for it. How he seemed to not react at all to her turning with the loaded gun and it being pointed right at him just struck me as odd.
