I really don't care what race the Wests are. I don't understand if people are complaining about it. I know the source material, and there's nothing about the character of Iris West that makes her have to be white.
Well because Wally West, the greatest speedster after Barry Allen and one of the all time greatest comic book characters is white, Iris is his blood aunt. Oh, and Iris has always been drawn white in the comics. This is how she looks. Black is kind of the polar opposite of that and pretty deliberate.
HOWEVER - as long as they get Barry Allen right, all I really care about seeing is a good show at this point. If the show is good, I am not going to complain much about black psychologist step sister Iris West. I just want to see a good, well written, entertaining and fun show that shows how awesome The Flash and Barry Allen is, so despite what we have heard so far, I am taking it all with a grain of salt and still hoping it will be good.
That being said, I am betting there's no way they'r going to make Wally West black, I really don't think there is any way they are seriously going to make such a major change to him like his race (hey, remember when WB wanted Marlon Wayans to play Robin since he was to be black in the potential third Batman movie helmed by Tim Burton that eventually was scrapped and became Batman Forever? Wouldn't be the first time WB has opted for a black sidekick that's usually portrayed as white in the comics
), I'm betting they don't include him at all on the show and that it's primarily about Barry Allen as Flash (which is how it should be for a looongtime anyway, even if they are going strictly by the comics, so I'm cool with that, and it's an intelligent thing to do). Whoever is Flash should be "THE Flash" for the series and they should build it around that character - The Flash is not the Green Lantern Corps so there is no need to have multiple versions of a singular character. Plus...Wally took over for Barry. In some versions it's kept a secret to the outside world that Barry even died and that there is even someone else or new under the costume as far as the outside world is concerned....with a black dude replacing a white dude...it's pretty obvious something is up, so they may have written themselves into a corner with that one if that is the route they choose to go.
Ernie Hudson, I would have never thought of him, but it'd be a great casting choice. He's one of those great actors who's never really gotten the attention/respect that he deserves.
Good actor any show should be happy to have. Should be interesting to see where this goes.
