Now, Zhao finds himself on the run from the thugs out to kill him and the police, and it becomes a cat and mouse game for Zhao to stay ahead of the pack.
The film has a good premise and could have been so much better. I believe the director is to blame. The performances from most of the cast lacked enthusiasm and better editing could also have resulted in a faster paced, more exciting movie.
There are a few very good action sequences, but this didn't entirely compensate where the film lacked. Towards the end it became generic and predictable. 'Explosion' had the potential to be a true nail-biter, but it somehow missed its mark. It also wasn't believable that the characters couldn't kill their enemies despite perfect opportunity.
Regardless, 'Explosion' was nevertheless still an entertaining movie that kept me interested throughout.
