I like old OVAs from the 80s and 90s so I have a high tolerance for crap (I even enjoy it a lot of the time) but this was pretty bad. Just for fans of the manga, I guess, but there's probably not too many of those anyway. The plot was stupid (derp let's find the LEGENDARY BLUE FISH) and didn't go anywhere. The climax was pretty laughable and ended abruptly. Very bad and not even entertaining aside from an unintentionally funny rotating naked couple at the end. Sigh. I gave it a 3 because the animation and art are passable and I guess someone putsome time into this so I feel bad giving it a 1. That doesn't mean it's enjoyable, though.
