This movie, just like the series had the typical stone age humour attched. They could have taken more time to develop the story, (they took a half hour plot and streched it) but instead used several musical numbers for filler. While the movie itself was as enjoyable as the series, you are left with a sour taste, as thoese music numbers were just BAD!!!
For a true fan, this is a must for your collection. But beware, and be prepared to fast forward over parts.
