4.5 rounded up, as there were a couple of stories I skimmed/wasn't fussed on. I must admit to watching the animated movie version of the opening story before reading this (due to availability through library), and they have quite a different feel to them. This is more violent, as Damian and Tim get off to a REAllY bad start, but having read future stories first it was good to get the background to their relationship. Damian's a little shit - but I rather like that about him. He grew on me over time, and a lot more stories that took place after this one. 
 I've read a lot more Tim as Red Robin or with Dick as Batman so enjoyed the stories in this one with him as Robin to Bruce's Batman. The future story of Damian as Batman was good too (view spoiler)[although unless a Lazarus Pit brings back Damian, that won't happen now (hide spoiler)], as was the story with The Knight & Squire.
