I read the Grant Morrison run a few months before the show came out. If I had not, I don't think I would appreciate or like the show that much even going in with zero expectations. But that's just me. I have no idea what Doom Patrol is like outside of the Morrison run, but there's a lot of elements from the Morrison run that's in the show. I'm shocked they pulled some of them off for live action. Also, Elastic Girl was new to me in the show, and Cyborg was a bit bizarre being in the crew, but I can see why the showrunners did it, and they both fit in nicely. Season one was a lot of fun so far and I'm looking forward to season 2. I highly recommend the reading the Morrison run on Doom Patrol. It's fantastic.
