Ooof. Struck a nerve there...sorry about that. Wasn't trying to rain on the parade for those that are into this...as for that "combination" lessening any impact the design has...well, it's more an observation than a criticism. If the design is meant as some kind of visual callback to the whole genre of "killer robots" as you point out, then yes...it's a pretty successful design. I guess it's just not "wow'ing" me right off because of those visual tic's are a little too obvious. But...I won't be surprised if after I get a good view of this thing moving around and talking and whatever else it's going to do in the movie, I'll be right on board....
...and speaking more to influences, just saw another one looking at these pics. Is there a little "destroyer" thrown in that mix? Could that be a bit of a plot point? Stark used a little Asgardian influence in the design there that got away from him? Now see? There
is something fun going on here with those visual influences...
