>>212562380 (OP)Pretty easy when you have watched several movies, its like someone tips you for doing something slightly illegal and says its legal then blinks at you 50 times. Bad acting comes in every type like "the not even trying" (underacting) and the "overacting", overacting can be a bit more subtle, because in some scenes it can be a comedic relief or actaully fit even but you can clearly see it when you are used to it. Bad acting also implies wrong type of outbursts, horrible body language for the moment (the scene), no engagement to the character or no feel for the character they are trying to play.
As others have said yes gal gadot is a horrible actress and you can see it in every scene she is in.
