This season opening was ... off.
Season 1 was largely great. Excellent storylines for most characters, everyone had some character development and felt believable, I was really a fan of the initial Young Justice cast (with the exception of Rocket, who I would have enjoyed if she'd been placed earlier on).
But this? Doing a time-skip (5 years?), seeing four different Season 1 Young Justicers not appear (Kaldur, Artemis, Red Arrow/Arsenal, Kid Flash), breaking up at least one longstanding couple and getting a mix of new characters and apparently Young Justice becoming a multi-team black ops unit, etc...
It's too much at once for a season opener, in my opinion. That doesn't mean it won't be justified in the long-term and we won't get some closure/ideas/explanations, but still. Too radical.
