Since we never really got much post-Crisis Robin!Jason in the first place, and he's more often than not retroactively written as being more of a bad seed than he actually was (stealing the Robin costume in Nightwing Year One vs. being given the Robin costume in Batman 410).
Mike W. Barr wrote post-Crisis Jason as closer to his pre-Crisis incarnation, so I was also hoping to see more of an amalgamation of the two, or at the very least something a bit closer to post-Crisis Jason.
It was also nice to see a young Jason!Robin not being written as constantly angry, "thuggish", punk-like, etc. It seems like too often many fans, creators and editors forget that Jason as Robin was heroic and did heroic acts. Thankfully, Barr didn't forget.
( Jason was a Good Robin! )
