“John Wick” was a bit of a surprise film last year. Nothing against Keanu Reeves, but his involvement with a project isn’t always the most indicative of quality. Who would’ve thought that a film that utilizes a makeshift martial arts term called “gun-Fu” would actually not only be good, but kind of great?With the film’s success, of course, comes a sequel, and to be honest, that’s where a bit of the concern lies.
