The Twins Effect (2003).
I hardly know where to begin.
For a start, I suppose, there are no twins. There are some vampires, and a league of vampire hunters. Some infighting amongst the vampires ensues, with the vampire hunters (and one of their sisters) caught up in the middle.
There are some amazing scenes with Jackie Chan.
If I had to have one word to describe it, the word is ‘goofy’.
