JLA is probably not the one you’re thinking of. It’s Batman, Lobo, Atom, Black Canary, etc. Strictly kind of B-list, a half-hearted attempt at what Giffen/DiMatties did is my guess.
Orlando is a weird writer. Sometimes he feels like the next big thing and sometimes his stuff is very generic, and it even can be within the same issue.
In general I think there are too many reboots and creative team overhauls for team books to really work anymore. Those books need more time to marinate.
