"Habba Habba Zoot Zoot"... seriously, all I saw was that AMV and bought the series.
I remember watching the first OAV 1 episode and thinking that my then-12 year old daughter would enjoy this...and then I hit that final scene and said "No, I don't think so!"
No doubt that the Wanderers version is more adequate for kids, although the OVA is rated 13 and up, if I'm not mistaken.
Let me put it this way: even if I decided it was okay, my wife definitely had objections. And if the mama ain't happy...
