I really, really liked it.
So far, it seems like its DC's best attempt at a television show in a very long time. While they made some changes here and there, the brunt of the story is there, Barry actually is the Flash (as opposed to whoever the fuck was in Smallville; it sure as hell wasn't Supes), there's tons of potential for the villians, several of his rogue's gallery have already made an appearance (or at least have been hinted at; I loved the sign in Star Labs especially), and they're even including some of the cooler aspects of recent comics in the story from the very start.
All in all, looking forward to seeing what they do with it. It's not going to be a boring emofest like Arrow, and it doesn't look to be a teen emofest like Smallville, so it's already miles ahead of the pack.
At the end of his comic in the 80s, Barry goes to live in the future with Iris(or is it the other wife?), the 30th century, where they have Twins. One of the twins has a Son called Bart Allen, who grows up to be Impulse, travels back in time to the 20th century, and then Kid Flash and then Flash... And that's who was on Smallville.
"Impulse" not "Flash".
Bart's mother actually had a fling with Captain Boomerang, which is how Bart wound up with a Super speedster Brother called captain Boomerang Jr who could not make up his mind if he was a hero or a villain.
