Between the chrome and the leds that seems to come from a custom gaming computer, yep, he just looks goofy. I was surprised because you know, usually they dial back the goofiness in the supers movies.
In general terms, I don't like they are going to do this movie without doing movies for the rest of the new superheroes. I think Marvel did it better, with films for Ironman, The Hulk, Thor, and Captain America. Yeah, Hawkeye and Black Widow didn't have movies but they are just 'highly skilled humans', you don't need a lot to understand that. And they are doing it again, with a Dr. Strange movie before using him in the other films.
But I would need a movie to explain why there is a cyborg guy as silly as a Borg in the universe presented in the Batman vs Superman movie.Same with Aquaman. Another reason is that they will have to rush the character motivations, background and B plots of each new character into the film, making very possible to do a rush hack job, if you do an origin film you can establish their origin, personality and what drives the hero in there.
