a) I haven't read Year One, so I can't judge it.
b) That's an earlier work anyway. People can decline in quality you know. Romita prioritises speed over accuracy.
For the record, I didn't mind Bendis, but the art on the last couple of arcs before he left... ugh. Shame too, as those issues had Young Justice, Supergirl, both Superboys and Brainiac 5 as guest stars.
