Oh yeah, the CGI looks pretty awful. The lighting in the desert scenes (which I assume are a response to MoS criticism) belongs in a CW show.I really.. really hate being that guy, but like this..is..wb. We have zero evidence that this isn't another giant clusterfuck being smeared over with hype trailers.
On a more contained, but concerned note, I cant be the only one that noticed the CGI ...off. Like not quite ps2 cut scene, but its sooo obvious that his action scenes are all cgi and the suits been redone a couple times in post. Theres a brief second in the trailer thats practical, I think hes just standing in the batcave and it looks nothing like his weird ultraslim bright red bird neck suit.
I don't want it spoiled for me, but the flash 2 betrayal twist seems increasingly evident. Im assuming flash 2 cant accept that his mom hasd to die and flips out. All the action in the trailer seems like an early or mid movie battle.
I wouldn't put it past them to have a Flash vs Flash fight for the reason you mentioned, but I do doubt that past Barry is secretly Reverse Flash or some shit like the internet thinks.
