I really don't think this show could be any better. I'm absolutely flabbergasted by it. That scene with Flash on the roof with Iris, and the voice changing, and just the directing/camera angles and where they're standing, it's as good as it gets from a technical standpoint. I seriously don't see the point in WB making a feature film of The Flash. This show is really giving that notion a run for its money. The only real improvement would be the budget and bigger explosions. That's not what makes a better story.
I'm beginning to think that television is the perfect/preferred medium for telling superhero stories. You just have a lot more time and more to explore... It's truly the live action version of a comic book. New adventures, new stories, endless content, every week. You can't get that with film. With film, you get a Batman trilogy and then it's over, and you waited 3 or 4 years for each one. Then you have to reboot it and start all over again with a new story. And the trilogy never explored Riddler, Penguin, Mr. Freeze, and so on. You can't sign Christian Bale or Robert Downey Jr. to a 12-movie contract... they'll want out, and poof, the story's over.
Freakin' Arrow and Flash are providing us with dozens and dozens of hours of content, and it's all coherently linked as one thing. In five episodes, we've seen Reverse Flash, Gorilla Grodd, Captain Cold, Multiplex, The Mist, Plastique, and the Weather Wizard... What other medium besides comics and cartoons can you see that much so quickly?
