As I recall it’s three issues, and those numbers sound about right.
It’s a story of Thor leading an Asgardian invasion of Hel, and obviously this movie is going to include similar events, but there seems too much other stuff going on for Skurge’s part to have any decent amount of screen time. I mean, #362 (or whatever) is more-or-less a Skurge comic, with Thor as a supporting character.
It also has more impact when you’ve got 20 years history of Skurge being a loser. That’s a lot to set up in one movie
