imagine a cockroach ...
a girl ...
and hundreds of baby cockroaches .
these baby cockroaches have same mother(that girl) , but not same father . and they are immune to insecticide .
now put that scene in the end and make it your happy ending .
what do you expect from such anime ?!
it's exactly as you expect it !
the story could have been great if you exclude that happy ending .
for art and sounds you can not expect something more from something that old .
the combination of animation and live action make the art look even worse .
the supporting characters were more developed than the main characters .
our heroine was the less developed character .
from the beginning till the end you can not understand what was her reason for doing this or that .
and for enjoyment ...
if you could take the first 1 hour , there's less than half remaining .
althought it has some enjoyable scenes and that scenes really worth watching .
the problem is that that "some enjoyable scenes" are less than 15 minutes .
