I like it if it's done well. And I wish they would include other holidays other than the cliche 'christmas episode.' But some of them are fun and not too in your face.
I actually like it when they do a Japanese festival episode better. I think those are fun to see the traditional holidays more. But like I said, if it is a well done and not a too cliche giáng sinh one, then it's not bad. It's also fun to see how holidays are celebrated differently. giáng sinh is thêm of a romantic holiday and Valentines ngày the girls give guys the Sô cô la :)
Here's a câu hỏi that I just thought of, does Nhật Bản celebrate anything like Halloween? I guess they don't since I can't think of an anime that has it but, that would be fun to see.
I enjoy them if they are well done. I have seen some that feel thêm like 'cheesy fillers' than an actual attempt at acknowledging the holiday. In those cases, I would rather they not bother. However if they are well done they can be quite fun to watch. :)
