Mmmmmm what can I say about this one.... Don't bother with it perhaps? :P Unless you really REALLY love Shounen-ai. Cause I can see how people who really like watching those anime would like this one. Hell I like watching that stuff but this one just didn't do it for me. Cat boys in chains are generally amusing to me and enjoyable the the one in Loveless was rather annoying and very unlikeable to me.
Like most anime it was made before the manga was finished thus resulting in a shitty outcome. So I'll probably be picking up the manga someday to see what really happens at the end. Or at least give me a little more satisfaction or who knows more disappointment. :P
I will say this though if you like animal people (cat boys) you'll enjoy this! :P As a lot of anime fans tend to LOL
