More to the point they posted an image of Bats from the previous film. Like an actual publicity still. And basically thought "let's just do the flavour of the TDK poster again"
I saw the trailer in front of Jungle Book and the CGI is more convincing in 3D. Pretty much everywhere but especially the best VFX shot of the trailer, Durotan's close up in the tent, it looked much better.
If the VFX actually are improved in the finished film (which I hope lol) then I think the 3D is going to help. Having seen the trailer in 3D makes me actually want to see this in 3D. Never thought I would say that lol
And by better you mean the film itself, not the RT score or the amount of money it makes. Still, to top that over BvS it has to make $800 million, I doubt this can make that. Would be great of course, because I'd love to see the Naga brought to life, but still.
