NO! I liked him MUCH better in the first series. I don't think he looks cuter at all. I think he looks just worse, and if anything I was disappointed. I hate it when the animators try to make him look like he does in the manga, it's just not the same. T^T
This is also the reason I can't watch the movies because the animation of the characters just plain BAD!
Sesshomaru is not meant to look cute, or at least not All the time. To me it just isn't right and ruins his cool facade.
Eh....I think he looked MUCH better in the original series...loved the screenshots....BUT in the Final Act the animation was improved (it was made 5 years later, duh?) so I was able to get better details of him I guess. Besides he had more on-screen time which I did not mind at all!
