Trailers that are just cinematics usually get a pass from me. I want the trailer to leave me with a feel of what the game is like.
Normally I feel this way, especially about AAA games where they're practically movies already.
But on the other hand, a good cinematic trailer can grab me in a way that just slamming screens and incidental music and buzz-words/feature points won't. Do not discount the value of interestingly arranged visuals and a killer soundtrack.
I mean, consider Darkest Dungeon's initial trailer. What was actually a story-like example of gameplay was interpreted purely as a cinematic. Would Darkest Dungeons have grabbed a body's attention the same way, if it had just been screens of action, broken up by black screens with white text shouting WE DO THIS THING.....(gameplay) AND THIS.....(gameplay) CATCHY TAGLINE. I don't think so. Especially if they hadn't had dat narrator.
Sometimes expressing the tone and the vision of the game is more important than expressing the gameplay. I always want to know exactly what a game looks like, but rarely do I make a final decision about gameplay just from a trailer. That's why I always want to read people's impressions, because they'll explain actual gameplay in a way that trailers never will. (Also I don't really do LPs.)
Tone though....tone is something I think you can establish quickly from even bad trailers. And so when someone sets the tone for their game in a way that just grabs my imagination (Hotline Miami), I'm willing to believe that their gameplay has the same level of craft and thoughtfulness.
