Ang Lee has always been a visionary director who has challenged conventions with certain genres. While he doesn’t always hit a home run, Lee can at least be appreciated for wanting to take ideas to help usher in classic films. “Gemini Man” should have been a slam dunk. It would have been a slam dunk. But as a film, it’s so much more a concept meant to do pretty much everything but tell a story that’s engaging. It flexes its CGI, as well as Hollywood’s current fetish for de-aging stars and trying to find ways to beat mortality for the sake of cashing in on them as long as possible.
