The John Wick franchise itself is arguably to blame for much of this. Since 2014's "John Wick," the character has simply become more and more overpowered, besting entire hordes of thugs to the point that /Film's Witney Seibold summed up 2023's "John Wick: Chapter 4" as proof that an action movie can have too much action.
But that doesn't mean the first installment was any sort of tame action outing. The film introduced Reeves' hitman as an unstoppable force feared by criminals the world over. In fact, John Wick kills a total of 77 people in the first movie as opposed to 51 in the sequel (by the fourth installment he was up to 140). The body count of a "John Wick" movie has since become a defining element of the saga, which is why it's particularly surprising to hear that the script for the first film was originally a much different movie in that regard.
