Other mistake: When Dr. Doom glides into Silver Surfer's cell, Surfer is resting on his hands and knees, and the surfboard somehow gets under his hands and left knee without lifting them off the ground. (00:15:15)
Continuity mistake: When Reed, Sue and Thing depart to battle Dr. Doom, Thing is wearing a sleeveless shirt and tights. When they all jump out of their plane, Thing is shirtless and wearing trunks when he begins sliding down the tree, and then wearing the shirt and tights again when the camera returns to him.

Answer: Gleaned from the Internet: Much of the negative reaction was due to the poor, simplistic, and outdated quality of the animation where the characters moved stiffly and clumsily through scenes. There were also some obvious animation compositing gaffs. The animation colors were also criticized as being overly bright and cheery and out of character to the established story's darker tone. The broad humor of the first season was replaced by a more mature narrative between the characters.
