Journey Into Mystery #646 preview
Thor was pretty awesome. If this first issue is to judge anything by, then Aaron's already shown that knack of being able to juggle the Viking/Norse Myth aspects of Thor as well as the cosmic/sci-fi vibe, which is important for any ongoing Thor writer, imo. Thor's characterization was also pretty good.
I also liked Fantastic Four. Fraction played it safe (which is good for the F4, especially right after Hickman's run) but it got me interested cautiously so. Actually more curious about FF than F4.
