Didn't Tim the creator of "Batman needs Robin to be his light"? For me it's a bit harmful for Batman's character to say that his sanity depends on a minor child, but I admit it's somewhat heartwarming take of Robin role, and I see many people, especially Tim fans, thought that it's a cool take on Robin role.
He also the first to have solo series and establish Robin as hero who can work alone, so maybe he's not as interesting as the other, but to say that he doesn't bring anything to Robin pantheon is incorrect.
