What issue was it? Since I was referring to the latest Detective--the one with Scarecrow (art by Tom Mandrake). There's this one splash page in which a flock of crows attack a group of Arkham guards--good stuff.

As for Don Kramer being generic well I can't argue with you there.
But then again, Paul Dini's stories are short, simple arcs so Don Kramer's art fits in real well. They're not life-changing stories, so why should the art be? That was my problem with Alex Ross. His work tends to exaggerate a simple story too much. Art and story shouldn't distract from one another.
The artists on Tec and Batman may be generic (Kubert, Kramer), but to me it's good enough. Kramer's art compliments the story pretty well.
I don't like how he draws Batman though. However, I do enjoy his Joker.
