From the World of John Wick: Ballerina
The concept of a spin-off can be a fun way to expand on a supporting character the audience is already familiar with but here we would get to spend more time with them and see the same universe but from a slightly different perspective. However, the spin-off in mind for the John Wick films takes the concept but chooses to shoehorn in a completely new character, which goes against the premise but could allow us the chance to see a fellow assassin actually carrying out their profession, something we never really saw Wick do. Sure, we saw him put his skills to the test as he went out on revenge but every film was him going against the system in some way shape or form, with the brief exception of the Rome sequence in John Wick 2 . The idea still had potential but then the filmmakers for the not so neatly titled From the World of John Wick: Ballerina , decided to make this a straight-up revenge film so there goes any chance of seeing a professional actually do their work to the letter...
