Action movie
The genre is usually about a resourceful hero fighting against high odds. These movies often have life-threatening situations, a villain, or a chase which usually ends in victory for the hero. Action movies became cheaper and easier to make as computer-generated imagery (CGI) changed. Action sequences and other visual effects that needed stunt crews were more expensive in the past. Reactions to action movies with a large amount of CGI have been mixed. Some movies use CGI to create events that are not realistic and are unbelievable. Action has been a part of movies for a long time but the "action movie" genre did not start until the 1970s along with the increase of stunts and special effects.
