Netflix shares are down about 3.6% this morning as investors digest its better-than-expected Q2 earnings, and slightly disappointing subscriber growth numbers. But CEO Reed Hastings remains sanguine, telling CNBC that with a sub fee of $7.99 a month “our model works great as is.” All of its original shows including Arrested Development are hits, although he won’t offer statistics to say what that means. “We just want to get more and more content,” he says. What’s more: “We should have some failures, or we’re not being adventurous enough.”
