It’s weird that praise is never questioned but the slightest criticism always is.
I don’t see anyone here making declarative statements like "this trailer proves the movie will be great, or “this trailer proves Glover has nailed Lando.” I mostly just see people saying “that looks cool.” You don’t need context to think something looks cool. Even if in the final film the cool looking thing is out of place and ultimately bad, it can still look cool on its own.
