What do you think about Formula E?

I've watched a couple of races on TV, found them uninspiring. Seems to be about the same level as Indy Lights, but for old drivers from lesser series (no idea why I think that). The young shoes seem to be tearing themselves up in F3. Interesting to me that NPjr won the championship, ex-F1 pay driver and Nascar truck driver, also Scott Speed. What makes me ask is that people seem to be touting it's "success" but as far as I can see it's main success is that it just hasn't failed yet.
