I think Bendis is VASTLY overrated. He's not even in the same orbit as Morrison or maybe even Snyder. Here are the things I would do if I didn't hate Tim Dreck so bad and wanted him dead:
(1) I'd bring his parents back into the picture--maybe even give him new siblings. Imagine him calling the 'Cave to tell 'em he can't go on patrol because he's stuck taking care of the Drake's new baby.
(2) As an extension of (1), I'd give him a life outside the Bat-Clan that he works to maintain. Tim himself said several years ago that he didn't want to be Robin forever. Then he should question whether Batting around is something he wants to do.
(3) For Heavens' sake, pull BACK on the Reed Richards/Tony Stark Super-Genius crap. He can be related to as a computer nerd, even a talented hacker--but this Intellectual Omega-Caste genuflection and making everyone else around him look like idiots is alienating a lot of people (like me) from him.
(4) Being an "Olympic-Level Gymnast" takes a LOT of training. Even Dick Grayson is probably not an "Olympic-Level" gymnast. To just SAY that Tim is this great gymnastic wonder without SHOWING his struggles to get there is very off-putting. It's like the Greek myth of Zeus getting hit in the head with a hammer or something and then Athena springs forth from his forehead, full-grown and all-wise.
(5) He should have a place besides just "The Only Smart Kid". I have a big problem with Dick and Jason (and even Bruce) suddenly turning into complete imbeciles whenever he's around.
(6) The writer just saying something to the effect of: "Tim is the true heir of Bruce Wayne." The big rule of writing is "Show--Don't Tell" and some fanboy writer telling me that does not show me why Tim deserves that place more Damian Wayne, the biological son.
And this is just the tip of iceberg for all the fixes Tim needs. I could come up with a LOT more.
A lot of it all boils down to DC's LAZINESS in dealing with Tim. They want to shove all these characters into pre-selected slots and roles: Dick is the athletic one. Jason is the homicidal one. Tim is the smart one. Damian is the one with the bad attitude. Duke is the black one. Babs/Steph/Cass/Harper are the girl ones. We're getting nothing beyond round pegs in round holes and square pegs in square holes. Lazy.
