I'm going to comment here that while "submit it" is indeed the most direct way to gather significant amounts of feedback, it needs to be realized that for such a movie, making it to publication is still very much an uphill task.
Playarounds very rarely get obsoleted, nor do they get published together if they share the same goal. Obsoleting a playaround requires having a very definite mark of improvement over the previous movie in terms of creativity (or technicality in some cases).
In this particular case, the submission would be weighed against a TAS with a Star, a Recommended for Newcomers flag, Innovative and Funny TAS awards, which is still considered a highly rated, great creative piece of work. That is a very high bar to be measured against, and if you want to contest against it, you need to be sure that you bring a peak product of creativity to the table.
And honestly, as soon as I saw this video posted here, I noticed that it was not up to par (in terms of creativity and humor). But it was
submitted anyway, and (quite predictably, tbh) the thread became a bit of a mess. I would have recommended against submitting it, but alas, I was too late.
I guess the bottom line is: trying to get a playaround published (either alongside or obsoleting an existing one of the same category) is
really hard. In this case, it might even be practically impossible. The published TAS has a few flaws of jokes that haven't aged well, but coming up with something better is still an
enormously difficult task.
