It lost a lot of it's charm

How is it any different?

It looks so much stiffer, to me at least

To each their own.

the art direction changed and i don't like it

Different strokes for different folks. It seems our generation is getting saltier quicker. Not you, just as a whole.

literally different strokes, the strokes are larger in the older stuff

t-there's a few harmless touchups?

The animation is stilted. Its honestly not a great example unless you know what to look for, but basically instead of things squashing and stretching, they just go in straight lines without changing shape, because they use tweening to move an image along a path instead of drawing it multiple times. This can make animation lose its personality if used too much, like in the case of Family Guy or Johnny Test.

That's been a trend since now pretty much all 2D animation is done overseas.

i still am saltly about the change in animation with american dragon

Johnny test was a disappointment from the beginning

Oh, most definitely. I guess I worded that wrong. Johnny Test never had any personality to lose. It always used ****** tweening.
