Well, the only Bat book I've been reading has been Detective. I never cared for Morrison's run and dropped it awhile ago. But, like you, I have no interest in Batman RIP. As for Hush, I don't care for the villain all that much either. However, in Dini's hands, he might be interesting. I say if money is an issue then drop them until the Hush arc is over. I plan on dropping Detective until the RIP storyline is over and I'll probably go back once it's over. Even though it's your favorite character, drop the books if they're not interesting you.
