Some of the negative reactions were quite overboard.
I alpha tested Kingdom Come: Deliverance and the first thing that was focused on was the city layout/environment, I remember the models being very dull with funky looking hair, really awkward blank expressions and stiff animation which is actually quite common since those models are used as placeholders. Yes, Shenmue III could have had a warning that it was still in development and a work in progress, but I think some people fail to understand what development stage is. I was quite satisfied with the teaser.
