Honestly I'm not sure I'd rank Twilight as some of their best efforts either, though it's certainly not the worst. But I'd say the real problem with it is that (like a bunch of the other stuff that's been mentioned, including a couple that I think *are* some of their best efforts) is that it doesn't work as well if you're not already familiar with the characters and setting. That's why I'd favor Symphony as a place to start, as an excellent story that's also starting up a new cast for the most part, so there's not going to be as many "Who's this joker, and why should I care?" moments.
