JJ absolutely nailed the characterization of Clark, Lois and Lex. It was better than I've seen from any live-action portrayal thus far. And his last draft of Flyby was very solid, especially for 2003 as it featured a lot of things that hadn't been done in the genre yet and have now become staples. The stuff like Krypton being a war-torn world instead of fully gone and having the Zod knock-off as a villain was a mandate of his commission, and frankly was handled well enough to not be a deal-breaker for me. If that movie had been made by a competent director, I fully believe Supes would've been at the forefront of ushering in the Golden Age of CBM's instead of chasing its success.
