The thing with Tim Drake is it's been many years since he was a good character. He was one of DC's best during the 90s and I'd argue his solo was better than the main Batman books during that era. Then after Dixon left DC went about systematically destroying everything that made him a compelling character by killing off or writing out pretty much his entire supporting cast, especially his father, and turning him into a mini-Bruce. At least he still had his past to build on, but then the reboot happened and that was wiped out too, leaving just the boring, irrelevant mini-Bruce who only exists because DC can't seem to let go of any male Robin. He's been a shell of himself since 2004.
