Personally, I think it's underwhelming, though not horrible.
I'm sure it will look much better in the finished movie. The Iron Man suit didn't so great until all the visual effects shots were completed.
Yeah, that's true. It's never the best idea to judge an outfit on the basis of shots like this.
But Jarod Russell's
Iron Man/ Batman offspring remark perhaps best captures the apparent lack of originality this suit seems to have.
