The Grinch meets Halloween. This does sound like an actually pretty good premise. The involvement of Dr. Seuss, Gerard Baldwin and Friz Freleng as well as many talented (voice) actors certainly offers more hope, but the outcome is a bit of a disappointment I must say. The main problem for me was that, unlike the title suggests, these 25 minutes felt a lot more about an annoying little kid with glasses (and his family) than about the Grinch. This movie here was made roughly 10 years after the very famous Christmas-themed short film about the Grinch and the latter will have its 60th anniversary soon. It is also superior to this one here. It has a bit of everything: comedy, drama, horror, family movie..., but sadly, it does not really deliver in one of these genres. The animation is pretty similar in terms of style and level to the 1966 movie I mentioned earlier, so it's not exactly a modern work for the late 1970s. Then again, this decade was fairly disappointing in terms of animated (short) movies anyway. This one here is no exception. Not recommended, not even during Halloween.
