All the stuff with Sov spies littered around, that awful bit where Dredd mercs up a gulag and the absolute drek that was "Blood Trails".
Ugh, I really don't like this.
It feels very Garth Ennisy - a few supporting characters from the past brought back clumsily conspicuously in run-in stories (Giant, Guthire, even super-obscure guys like Judge Ocks) in order to be put over the butcher's block in some sort of piss-poor attempt at pathos. That's exactly the approach Ennis took in the build-up to Judgement Day, and it both screams "LOOK AT ME! I KNOW DREDD'S PAST" and "I CAN'T QUITE GET THE HANG OF THIS JOHN WAGNER FAN-FICTION LARK LADS, SEND HELP ASAP".
I realise that Rennie was going to be given the reins at one point - not to slight the man, he's written some OK stuff, but I'm glad someone else will probably take over Dredd from Wagner at some point (who wrote that Christmas story about the bleeding jesus doll and the extended flashback? That was fucking hysterical). The Sov stuff feels like an attempt to take ownership of the fates of certain characters (with all the subtlety of being face-diddled by a rhino) while building to Apocalypse War II down the line (yawn). This was something they did before in the 1990s, with that weird vestigial Chinese/American war buildup they shitcanned as Wagner returned.
Rennie's Sov stuff... well, god. It's puerile and political in ways that don't make sense. Redraw the costumes and some of the dialogue is so unintelligent and unDredd that it could pass for leftover Lawman of the Future strips. A legal eagle shouldn't talk like a bad parody of John Rambo, running off to Russia to engage in dick-waving contests with some bad racial stereotypes and the usual unwelcome "creepy guy in a wheelchair" stereotype (because as we all know, people with physical defects are bitter little creeps! Nice going, toofer).
Blood Trails is even worse - Vienna gets used as a women-in-fridges fucktoy purely to mess with Dredd's head (again!), some very good characters get tortured for not much reason at all (Rico's metal face is going to be a really awkward bit of continuity clutter that will probably ignored, I think) and the whole thing had art that was just entirely unsuited to a proper serious Dredd arc.
Not to forget how bloody embarrassing it is to paint Soviets as some sort of thread in a 21st century comic... it felt dated, a bit creepy and xenophobic and out of touch, all at the same time. It's coloured my thinking on Rennie a lot, even if he's done some decent Wagner-aping one-shots.
