I think you are too dismissive of people's opinions and gut reactions to things when they don't align with yours on occasion (maybe I do it too).
Like you said, there is only a few seconds of footage. What do people/capcom expect people to think? Have it both ways? If they love it awesome, if they don't, hey, it's only a few moments, don't judge us.
The whole point of this little teaser is to gauge people to see what their reaction is to this early look. Your first gut thoughts when you see something are most times the most honest. There is nothing else on display to judge but the few snippets of gameplay and graphics.
I am just speaking for me here:
Gameplay is king, but graphics matter more than you are giving credit for. And more in depth to that is feel, physics, the art direction. If i love the mechanics, I am going to be looking at this stuff for a good long time. This all matters to me. I like looking at good art and animation. Maybe these people are simplifying saying it "looks shit", when they don't like the art or how these guys are animating. i admit, it's annoying.
You say SFV looks beautiful, just from that teaser. Just those few moments? Why is your positive quick take more acceptable? I don't think it does personally. It looks rough (like a year or so out), but they put it out there for people to judge, so we shall judge.
Let me preface, I really like SF4. But just from they have shown,I wish they went in a different direction with art direction, and the physics and the inertia of how they are moving looks the the same vein of SF4. And those character models are not blowing me away. I have been playing since 2008. I wanted something different.
I am sure it will be fine with it releases. Models will look great. It will animate smooth. I'll be there day 1 of course. I will probably like the mechanics. But we are judging in the now.
I wanted a 3S like reboot (like what I wanted with Tekken 7, haha). My dream was doing like Xrd engine, models looking like the SF2 anime kinda. Maybe having a run, or just moving around different, dashing different. heavier jumping, but more explosion on take off. Things like these. Maybe it will happen on final product, who knows.
I would not be so dismissive of peoples gut reactions. Maybe they are wrong. maybe you are wrong. Maybe I am wrong. I do see your point when it's hyperbole and it's annoying. But there is nuggets of truth in there maybe.
Also on COD, I don't think alot of players post here, of the huge base at least. Just from people I know who play, they play for the mechanics and gameplay, not the graphics really. I think they all admit it doesn't look that great, but love that framerate. My brother moved to Titanfall and Destiny. I asked him why, he said he was bored of how COD plays, but he said he also wanted to play in a different universe and "it looks basically the same every year".
