Yeah, that's true. It's never the best idea to judge an outfit on the basis of shots like this.
I'm remember many fans were pissed about the second Iron Man superbowl trailer and complained how Iron Man shooting the tank looked fake. Of course nearly them ended up loving the suit after seeing the movie.
Not even the trailers won't have all the visual effects done in time. Of course if it sucks in the completed film, fans have every right to complain.
