I like this film, though haven't seen it since it's theatrical release in the mid 80s.  I remember being somewhat disappointed in it, largely because of all the hype it seemed to have at the time.  It think that was just a matter of expectations being high, but it remains the only film, other than GODZILLA VS THE SMOG MONSTER that I really like after the 60s.  

Also loved seeing Raymond Burr reprise his role (at the time I didn't even know there was a Japanese version of this film).  1985 was a good time for one of my favorite actors, not only did he do this film, but he started appearing as Perry Mason again in a series of TV-movies.
