Although the animation quality frequently was far from great and some guest stars and villains make more of an impression than others (particularly in the first season), 'The New Scooby Doo Movies' while not consistent and its flaws are more noticeable is one of the better Scooby Doo shows.
"The Frickert Fracas" is a hugely enjoyable episode. So far (re-watching the episodes in order after a long time), "The Dynamic Scooby Doo Affair" and especially "Wednesday is Missing" are superior episodes, but it is better than the decent but not great and very flawed actually "The Ghastly Ghost Town".
Particularly notable is Jonathan Winters himself, who is a lot of fun while not swamping the mystery, and Winters clearly has a ball as himself and even revels in his speciality of imitating old ladies (the grandma character is priceless here). Also the scarecrow, who is one of the series' better villains and the best one up to this point.
As ever with Scooby Doo, the atmosphere has a creepiness and the humour here is right on point, especially with grandma and the gem of a sequence with the giant wheel, one of Season 1's funniest and most imaginative moments perhaps. The dialogue is vintage Scooby Doo, and even with famous guest stars 'The New Scooby Doo Movies' (at least in the first season) was true to the spirit of 'Scooby Doo Where are You' and what made that show so great.
Music is full of energy and atmosphere, with a catchy theme tune and the voice work is top notch.
Only complaints here are the too-easy-to-figure-out identity of the villain and particularly the less than great and sometimes poor animation quality, with crude drawing and distractingly bad goofs that do outweigh some atmospheric colours and backgrounds.
In summary, hugely enjoyable episode of the series. 8/10 Bethany Cox
