It's cool as a one-off promotion to build some hype, but I think a lot of people on social media are jerking it off too hard to this, like it's the best thing they've ever seen - assumingly because the bar for anything live-action RE has already been so low, including some fans' standards for what's expected out of RE media in general.
Honestly, why and how would a zombie still be walking around a desolate Raccoon City for nearly 30 years (if that's what's being implied), especially out in the open like that? I get they're trying to show that the infected in RE9 act on memories, but this was a bit of a stretch with how long it's been. Kinda corny. Can't take that seriously.
Visually, it was mostly done well - so I don't hate it. I do agree it's already better than any of the RE movies - but again, low bar. I just can't stand overpraise from the general population toward such things that are really just "OK" or passable, just because it isn't absolutely dreadful.
I still think Capcom and who they work with can step it up, and be more consistent with the earliest games' established lore and logic.
