Casting another Superman does confirm what I've suspected all along about WB: they're full of Bantha poodoo when it comes to Green Lantern. Supposedly, Green Lantern is "too big" for Flash, but somehow Superman isn't too big for Supergirl? That's ludicrous reasoning and they know it. The cold, hard truth is that they're scared.
The WB doesn't consider Flash and Supergirl equal. So Superman and Green Lantern are too big for Flash, but neither are too big for Supergirl. Supergirl is too big for Flash too. She hasn't shown up there, and they aren't even allowed to mention that whole event. The closest they were allowed to get was Barry confused about how long he was gone for a second.
The cold hard truth is, they like Supergirl and don't like Flash. The Flarrow actors know this, and have expressed as much. Supergirl doesn't have that problem, even after she moves to the CW, she's considered greater and more important. Maybe it's just ratings, maybe it's because the Superman mythos hold a greater place in the hearts of old executive types, maybe it's because Supergirl is, critically speaking, a better show. Maybe they're just Ally McBeal fans. Not sure. Either way... Supergirl and Flash are not on the same level in the eyes of the people making decisions.
I agree that compared to Superman that Boomer is a lesser character... Which again is why actually having him portrayed by an actor now on Supergirl could portend a shift especially with LESSER characters like Boomer. If they can live with two live action portrayals of Superman on TV and in movies then why not two versions of Boomer? Notice, COULD, I'm not saying this is what is, or has to be. Just that it's not insane to suggest that loosening up with Superman of all characters might mean something for the wider array of characters.
There's no shift bro. They don't care. The actors know they don't care. Superman gets to be on Supergirl because Supergirl was made with a special deal, and even then, they couldn't show his face. They aren't even allowed to mention
Supergirl on Flash. There's no loosening up.
The only thing I would worry about, is if they'd be able to give Green Lantern a decent costume. But effects wise, after everything we've seen them do, he'd be a piece of cake.
Why does a costume seem difficult, but flight, realistic CGI, sci-fi locations and the practical effects that should go along with big energy powers seem easy? Is it because Flash throws some chintzy 30 second CGI sequence in once every 3-5 episodes? I feel like if you'd ever had to do those things, or pay for those things you'd see which ones were actually difficult and expensive.
Compared to the likes of King Shark and Grodd, not to mention the speed force effects, GL should be comparatively easy. We've also seen segments on Supergirl that are set on Krypton and Mars, with numerous aliens. Flash's finale included an light effects-heavy villain flown off by two CGI villains. Thus, I don't buy the "too complicated" argument for any character after what we've seen on these shows.
But he's not easy compared to them. Making a CGI beast is fine, because you do it all on the computer, and if it doesn't look human, it's okay, it doesn't have to. Also... those CGI creatures aren't supposed to be generating light, which makes the whole thing another level of headache.
But that's not even really the core issue. Putting aside Flash at it's best, Green Lantern can't get away with all the episodes and minutes where there isn't heavy CGI. There are simple TV effects Flash can do to make his powers happen to be a superhero without blowing up the budget. That's a lot harder a sell for Green Lantern. He becomes a different character when he isn't able to make big constructs when there's trouble. And it's bad enough when Barry gets sucker punched by something mundane, imagine Green Lantern, whose ring is supposed to protect him getting trapped under a bookshelf.
Green Lantern can't be shrunken down to TV size as well as Flash can. Look at Flash's Rogues, the most TV ready of all rogues galleries, Batman's included, imho. Look at Green Lantern's enemies... big headed psionics, death gods and lots and lots of other Lanterns.
Me personally, I'm all for a shrunken down Green Lantern, who uses his powers about as often as we see Grodd/King Shark/Time Wraiths. I'm down for that. Most people aren't though.
