I really learned to like Young Justice during its first season, glad to see they got a second. 

Superboy doesn't appear to have aged. Megan has moved on to some fish
dude. Beast Boy finally shows up (yeah)! The original Robin has
graduated to his Nightwing persona. I'm hoping to get to see Raven
and Starfire this season, too.

Great show. Hope more people start picking it up.
