What are your thoughts about the ‘Whispering Corridors’ series?

I revisit this series every so often and I absolutely adore the first one! That one is so gloomy. Makes me feel nostalgic for some reason. Those dark hallways. And it seems they used some find of blue/dark filter for the whole movie. Such an amazing atmosphere! Also feel that the first one also somewhat co-responsible for kicking off the Asian horror movie wave back then. To me it’s up there with Ju-on, Ringu etc…

The general consensus seems that part 2, Memento Mori and part 3, Wishing Stairs are the most popular. But for me nothing can top the first one.

I also don’t understand why no one picked this up and released a nice blu-ray boxset or something. Would be an instant buy from me!
