Which ऐनीमे या OVA do आप think has the worst animation?

For me, probably the cheapest एनीमेशन I've ever seen would have to be Sonic The Hedgehog: The Movie. This movie was released about the same time as Sonic Adventure (which I believe was in 1999), and yet it looks like it was made in the 70's.

Now mind you. आप don't have to hate a film to say that it has bad animation. आप can name a film that आप enjoyed.

I don't care how bad the एनीमेशन in Sonic The Hedgehog: The Movie was. It's still probably one of the best video game फिल्में I've ever seen, along with सड़क, स्ट्रीट Fighter II: The Animated Movie.
