Yes it was a little crazy. It had a nasty habit of blowing reds and yellows (for me at least) so you had to be careful with it
Anecdotally I've heard it was an entire batch of Velvia that went wrong and fujifilm flogged it off under a different name, and then realising how popular it was, started to re-release it. There's a good chance that might be complete balderdash of course. They re-ran it every year around sakura time in Japan, which is the only place you could get it IIRC. I still have a roll or two sitting in the freezer.
