I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
This has a lot to it, it's just wrapped up in the oddest trappings possible. I'm especially having a hard time grasping what's happening to Trainor, and I suspect the fact that I haven't read much Doom Patrol is a hindrance, as well. Still, what little I've read off the internet about the earlier series seems to indicate this, much like Shade the Changing Girl, is a departure from the original: it's meant to be a new take that stays true to the roots and general feel of the original series.
Don't read out of order, though, or else you will be super confused. Some series, I feel, could summarize and don't in order to get you read in order. I feel it's penalizing to those who jump on board later - and quite frankly a bad move as something coherent/summarizations would allow a broader readership if someone did manage to miss issue one. It feels like a money grab to me. Not summarizing Doom Patrol, or needing to read in order, doesn't feel like that in this one. (And, yes, I have the same complaint for Suicide Squad which I like as much; they could easily summarize and don't. Doom Patrol doesn't feel like a mad grab for money, while Suicide Squad feels more so like that. Suicide Squad penalizes those who don't buy regularly, because they could easily summarize and don't; Doom Patrol doesn't as it couldn't easily summarize. It's too bizarre to really grasp the whole thing in one page. The story itself makes that impossible, so I don't feel like needing to read this in order is just for the money: there's simply no other way to tell this story, and to explain what's happened before.)
Love, love, love!
