This is a change I've been hoping for, for a long time. The stigma I've seen around Vault movies has become really annoying. Just because it didn't happen to be entertaining to the people who watched it at the time of submission, doesn't mean it's a waste of time to watch and appreciate. You could have an extremely technical TAS, on a game that's inherently very boring to watch (maybe there's slow movement, or a lot of walking/waiting, long transitions, etc).
It's always seemed to me that people generally regard Vault as more of a dumping ground for boring movies that are still acceptable for technical reasons. A sentiment akin to "This is so boring, just put it over there with the others, out of the way." I recall coming across
this movie where the focus on entertainment was so strong, someone argued that it shouldn't have been made at all.
As I understand it, and believe, besides superplays, TASes are supposed to be about making the perfect/fastest speedrun for any given game/goal. There have been numerous movies that did just that, but then are ignored or overwhelmingly-criticized because it wasn't also entertaining.
Consider, that the shorted TAS accepted on this site, is in the Vault, solely because it was not entertaining enough. (hard to be entertaining when the run is less than 1 second long, and yet it got 63 yes votes)
