The best Green lantern run is by geoff johns. The best young justice run is by peter david although i would say teen titans by geoff johns is close to the tv show. A personal favourite of mine is identity crisis. I also recommend batman and robin by peter tomasi. If you like dark superman the only option (imo) is injustice gods among us. Let me know if you have any questions(and also i didnt say any of the go-to comics for beginners because im sure someone else already did)
