Actually its considered his best film on both sides of the Pacific by most critics and fans. I think the forum just wasn't as impressed.

I didn't like it as much as I wish I did but it had some strong moments and is overall a real fun film to watch. I think my issue is that it was kind of the granddaddy of "Mysterious girl with magic powers and connection to secret lost civilization" plot line that is really popular in RPGs so it felt a bit predictable but that's what happens when the film isn't released until almost twenty years after its initial release.
