One of the best of the series, and perhaps the best villian, Just fantastic, dark grisly dialog preaching the end of everything, when someone wants something to be 'forever' you know things are going to go bad.
Slimer gets some nice development , There are animation inconsistencies though, one of the ghostbusters is replaced with Egon when he was on the road and they were up a building for example, some designs could have been tightened up a little for the other ghosts but they are infrequent faults and the overall story, and the greatness of Samhain overshadow these with fantastic script and storytelling.
Animation - 8/10
Dialog - 10/10
production - 7.5/10
