This is the first issue of Uncanny Avengers I haven't outright enjoyed from beginning to end. Rick Remender takes readers back in time for a look at the first time Thor met Apocalypse. It's sort of like an interlude prelude chapter to "The Apocalypse Twins" that foreshadows the events in the present day.
Thor-centric tales are difficult to write because, more often than not, they feature some disagreement between Thor and Odin. Remender falls victim to this cliche and once again, Odin finds some reason to be disappointed in Thor.
As a side note: seriously, does Odin ever even like his son? It feels like the old codger is constantly drunk and looking for someone or something to unload all his anger and frustrations upon. It's one of the reasons I've never been a huge Thor fan, and it's also why Jason Aaron's current run on Thor: God of Thunder is so good. There's only so many times Thor's daddy issues can be exploited, and that quota was hit years go.
Remender is a master of foreshadowing and long-form narratives, so it's kind of a given that all the events in Uncanny Avengers #6 will have some bearing on the present day, but it still removes readers from the current-day story and stops the momentum Remender was building.
