I know I'm a fan of the series, so my opinion is obviously biased towards a "I like the series" position, but I just never understood the "I hate that it's become Bill Willingham's political medium" opinion that's circulated the internet.
I'll admit that the Israel analogy was heavy-handed (really, it could have been better left implied rather than Bigby spelling it out), but I find that people see political issues in this book where you really must be looking for them. The story is a pretty good one if you aren't constantly looking for this stuff.
