So a long time ago I saw jin-roh or wolf brigade for some people. A great anime OVA, but some how it felt like i was mising a big chunk of the story so I did some digging and found out that the anime is a prequel to a live action movie called "while waiting for the red spectacles". I am currently trying to buy the movie, so has anyone seen it? Is it good?

Kerberos saga is the denomination of the entire series that include:
a radio drama (the genesis of the storie) two live action movies (while waiting for the red spectacles and stray dogs) two animes (jin-roh and one that is in the making) manga adaptation and a line of toys, very expensive and I sure want one.
