Munster, Go Home is basically a 90 minute episode of the show but the film isn't well paced at all. I almost felt a little lost without the laugh track. They transition to color fairly smoothly but I don't see much reason to watch this when there are 70 episodes of the show to enjoy first.
It is equal parts interesting and disturbing to see The Munsters in color.
The movie isn´t as good as the show which is largely due to the fact that they were re-using a lot of stuff from the show. Which diminishes the experience somewhat. Still fun and entertaining enough for a nice afternoon.
