The clip was absolutely amazing and I agree with Vlad on why people are complaining about the clip, because there isn't anything to complain about. So, there wasn't any outright laughing... who cares! Her facial expressions upon waking up, the cute and subtle smile and the dog licking her foot was great.
If all of the tickling clips had outright laughing in it, it would become repetitive and not as much fun. As a percentage, I'd say that the laugh is probably about 10% of any tickling clip. There are so many other variables such as the position of the lee (i.e. restrained, free movement, etc.), the setting, the tool used, just to name a few, that make up great tickling. So, instead of making comments on something that is not there, pay attention to the detail of what is there and appreciate those details because someone, somewhere, went to great lengths to draw the scene for that clip, that way. So to the creators of Full Metal Achemist, bravo! My thanks also goes out to kjiron for posting a sweet clip that shows that a laugh does not make a tickling clip, the details do.
