I dunno, right from the off there was the whole comedy romance between Atom & Cobert, plus the whole thing with Animalmans clothes getting nuked!
Maybe there was a more serious side to JLE, but it always felt the same as the JLI/A book to me, which was never a real problem!
Lets not forget the time they tried to learn French.
Or the time Wally looked at Karas breasts!
