...I think the "do better" argument is quite apt here. Doing is trivial nowadays - anybody can draw and animate with little more effort than that involved in typing a critique. If not otherwise, then by taking the piece under criticism and editing it to their liking.
At the very least, any argument of "X and Y are wrong with the thing here" should be accompanied with "I would specifically fix X this way and Y that way" or the one making the argument is just plain lazy. It may take rare skill to act out a scene, so poor performance there may be critiqued without posting a YouTube rendering of How I Would Do It. It may take somewhat more common skill to sing a song like it should be sung, and YouTube is full of sad attempts at "improvement" already. But it takes no skill to describe a cool graphics sequence, and very little skill to create one (certain irrelevant final touches notwithstanding).
