You know, while the trailer for Justice League seems good enough (then again, Snyder's films have always had good trailers...), one thing really bothers me, and it mainly stems from the fact that they were too quick to do a team up movie.
Mainly, it's the fact that it seems like Cyborg's origin story is being crammed into the film and will be inevitably rushed.
Cyborg's origin is, in my opinion, one of DC's better origin stories, and one that I think could have been a damn good film all on its own. The creation of STAR Labs, Victor's incredibly prosperous time before his accident (being a star athlete), the sheer anguish of Silas Stone at the loss of his wife/Victor's mother, as well as his strained relationship with his son, the accident which nearly killed Victor when Silas was arguably at his most vulnerable, and ending with Victor becoming Cyborg.
A story filled with loss and tragedy when life was at its best so soon beforehand, a promising future torn away before it could begin, and the struggle of Victor being unsure of whether he's more man or machine. That in itself could be great.
Instead we'll probably just get a quick montage and have all emotional impact be ruined. Thanks Snyder. :/
