An Obvious Set Up
Another new foe for Thor is introduced in this issue, Mr. Hyde. Also, Odin promises Thor that if Jane Foster proves herself worthy, she may be made immortal and the two may marry.
This is a very wordy episode of Thor, without a lot of action - Thor and Mr. Hyde don't actually encounter each other (although Dr. Blake and Hyde do), and the story is left on a cliffhanger. The art by Don Heck also looks rushed, as if preliminary sketches went to inking without any polishing.
The Tales of Asgard story is more disjointed mythology than is usual, and seems like back story to set the stage for next issue, which promises the appearance of 'young Thor'.
The backup stories are, as usual, forgettable.
So, basically what we have is one big setup for next issue - Journey Into Mystery #100 .
Let's hope it doesn't disappoint.
