Yup, I agree. The dragon slayer shouldn't of had a good ending. Well, at least he finally learned his lesson and realized that dragons aren't evil. Yes, as usual there are always loopholes in TVB series. Such a short simple series yet they couldn't manage to make it flawless without any loopholes. I don't remember the themesong, it was sung by Benny right? I think he is an okay singer, he just needs more practice.
Is Charmaine in both Country Spirit and Plain Love 2? I haven't watched those series yet but I've heard the themesongs for both and like them very much.
I've seen the first few tapes of Vigilante Force but never finished it. I agree Kenix was boring, she was playing the usual character she always plays. I didn't like Benny's role in there. Judging from the first few episodes, I thought his character was kind of a whimpy since he didn't have the courage to confront Bowie about Eileen. And yes, Benny seems to only get secondary or supporting roles in modern series.
I think Eileen Yeow is from Singapore. She has starred in A Step Into the Past and At the Threshold of an Era. Maybe some other series but I can't recall them. She usually gets supporting roles though.
