The last season did have "Flash and Substance," "The Great Brain Robbery," "Grudge Match," and the World of Cardboard speech...and that's about it.
Overall, the season suffered from having the O7 Leaguers largely absent and hardly using any of the newcomers they'd built up in the previous season. At first, it felt like they were going to focus more on the villains - which I was down for since it never felt like they got their due and were just punching bags - but that just boiled down to Luthor obsessing over Brainiac and Grodd being witty and Tala being thirsty.
