This first series of films are at times slow and at other times a bit ridiculous but overall they are a significant part of the J-Horror phenomenon. If you are a fan of this sub-genre then you must watch this series. I've watched it again and find that I liked the 4 theater releases much better on subsequent viewings.
As of 2005 there's been a new batch of Tomie films, which I'm anxious to find copies of. I have a feeling that Tomie will be back again and again, just like Godzilla.
