Marvel's Thor: Ragnarok - Prelude

I feel like these movie preludes are usually pretty flimsy but I loved Thor Ragnarok so I picked this one up. It's dumb. Like 1/3 of it is a comic recap of the Ed Norton Hulk movie. Why. Is there anyone in the world who's like “Yes I'm going to see Thor Ragnarok but I need this quick prelude first because I have no idea what the Hulk is.”

The random old Thor comics tacked on the end are fun though.
