Why's it become such a seemingly negative thing to raise genuine concerns about a franchise you want to succeed? I waited my entire life for a Batman/Superman film and was pretty happy to debate why I reckon it's great with those who thought it was a trainwreck. I don't seem to recall telling anyone to shut up about it.
There seems to be some growing mentality amongst Shenmue fans that we should shut our eyes and ears to anything bad and just repeat the mantra of "la la la, not listening, it's gonna be great, they know what they're doin, waited ages for it, just be grateful, la la la!"
Can you imagine if it doesn't end up being good? If it's poorly received by both the public and media? Who's gonna buy it? We've already got copies reserved. Where are they gonna make the money needed for the follow-up? It's simply not a case of "anything will do". Yeah, we waited fifteen years for this. So it better be fuckin worth the wait. And the money.
As for Spaghetti, how are you not getting this? Why does any studio show something off? No, why does anyone show anything off? Honestly, just think about it. Maybe English isn't your first language, in that case it'd be slightly more understandable, but c'mon... showing off concept art is promotional material. "Checking in" on Facebook to a hotel in an area where there's a relevant event: promotional material. Appearing on a chat show. That's promotional. A video, work in progress or not, is promotional.
