That doesn't really make it better. I get that it justifies it... I don't even want to say "in-universe," because this is obviously some spiteful, perverted construction stapled on, not an actual continuation of the universe; "oh, they were all actors!" would be a sabotage in and of itself even were it not overshadowed by this atrocity—but it does justify it within the abomination of a movie they made.

It's still bad, though. If there were a Scooby Doo reboot where Daphne had a dozen half-human, half-dog abominations with Scooby, it wouldn't really matter how they framed it. It would be gross. This is the same thing.
