Bigger and better - this is the general motto when it comes to sequels, it seems. But is it always better to go this route?
Sometimes sticking to a formula that worked, is better. The first 'Shock Wave' had a simple premise and it was high profile entertainment. It was realistic and therefore more suspenseful. With 'Shock Wave 2' they attempted Hollywood style action sequences with lots of CGI. Although the action sequences are fast paced and well done, they are not necessarily better than its predecessor. Having said that, it is also not bad. It is thrilling and exciting and the stunts are incredible. There is no suspense here, though, and the film is not as intense as 'Shock Wave' was, and doesn't have the same emotional impact of the first film.
Andy Lau is back, but as a different character. His character, Poon Shing Fung, reminds us of Bourne in the original Bourne film, where he can't remember much and trying to unravel his past - trying to determine whether he is a good guy, or the bad guy. For most parts, it works well. Andy Lau is a great actor and the action sequences more than compensated where the plot lacked credibility. There's also an exciting 20-minute finale.
Would I watch it again? Maybe, but I do prefer 'Shock Wave'.
