I watched this series a long time ago on TV. I wasn't sure which part I watched (actually I'm not even aware there are two parts to this series). It was the one with Cass Phang singing the opening theme song (and I love the song soo much too!). I remember I enjoyed this series immensely. The series is made up of several short stories that centre around the supernaturals and incorporate Chinese cultures and myths into them. There is a lot of interesting things you can learn from this series about cultural beliefs and animism, IMO. They have some really pure romantic plots as well. I remember the cast included some non-TVB actors. The only TVB actors that I can remember are Gallen Lo and Cindy Au.
TVB Square provided the Chinese title as "聊斋." :)
I highly recommend this series. Actually, I myself hope to be able to watch this series again.
