Very good. Probably an overload of grandeur, they try to put in a few human touches and quieter parts, but it's generally so many vast, epic happenings that it all comes across as far larger than life and one kind of loses track of the smaller, human parts of the story.
What's probably the best single run of Thor is reprinted in the Thor Omnibus, covering Walter Simonson's run on the series from 1983 to 1987.
I followed the comic on and off up through 2011, but haven't read it much since. Jane Foster has been pretty scarce lately, but Sif was until very recently featured in Journey into Mystery. This short run had both a female writer and a female artist, so it explored lots of aspects that the male superheroes usually don't explore.
