Finally got to see this. The sequel to 2017's fun action thriller again stars Andy Lau, but the two films' stories are unrelated. That doesn't mean you're not gonna see Lau defusing bombs again, because that's exactly what's up in the first portion of the film. He and Sean Lau are both bomb squad experts and personal friends, as we get to know very early on. But events happen that force them to be separated and Andy becomes a wanted man.
What transpires from this basic setup is an entertaining action film that's fast paced and almost gripping at times. There is a quick succession of shootouts and chases that doesn't let up until the film's 50 minute mark. It's somewhere in those minutes that the film's flaws become more apparent and the film less involving. You realize that the plot is as generic as they come, with some barely believable twists and turns taking place. And the action grows a bit stale with little inspiration from more successful Asian action thrillers, especially in regard to distracting special effects (so much CGI blood).
Still, there are individual moments here that make up for the film's shortcomings. The ever present threat of nuclear doom hangs over the proceedings, lending SW2 a darker feel than its predecessor. Pulse-quickening bomb defusing sequences offer some of the film's highlights, but that doesn't mean there aren't enough spectacular explosions here to satisfy everyone's destructive spirit.
Having said that, you still remain kind of underwhelmed after it's over. Just a sense that more could have been done with the plot and the film's intensity should have been more frequently on a higher level, given that the runtime sometimes feels stretched out. However, it's a good way to spend 2 hours of undemanding fun if you're up for it, just don't expect a great HK action thriller like we used to get until a few years ago.
