Modern action sequels have been in the news a lot lately. We just celebrated the 10th anniversary of ‘The Dark Knight,’ ‘The Equalizer II’ just hit theaters, and leaked video showed Keanu Reeves pulling a horseback stunt in shooting for ‘John Wick 3.’ Frankly, it’s a great thing that all of these films happened or are happening. ‘The Dark Knight’ is as good a superhero film and an action film as we’ve seen this century, ‘The Equalizer’ appears to have spawned a perfectly respectable franchise, and the ‘John Wick’ movies are resetting how we think of modern shoot-em-ups. It’s a pretty good time for the genre.
