Jurgen's run had the most annoying, wordy take on "Thor speak" imaginable for the first like 40+ issues,
The same 'Thor speak' that makes the character unique.
The same 'Thor speak' that (to an extent) they use for MCU Thor (albeit they've added humour to counterbalance his pomposity).
The same 'Thor speak' Aaron's Fem-Thor knock-off occasionally uses even though that's totally nonsensical.
and used the exact same battle formula for nearly all significant encounters until the Reigning started.
Is it a 'battle formula' where Thor is given a tough challenge and initially gets his crap kicked in only to come back AGAINST THE ODDS and win. ie. a good battle formula*.
*Maybe he should have just had Thor overpower Mangog and toss him into the sun.

The Reigning was then decompressed as hell, giving us a near-villainous Thor for years,
Agreed it was decompressed* and should have been the 12 issue mini-series it was initially conceived to be.
*Like current Marvel comics.
and then had a rush job nonsense ending because he ran out of time.
Marvel spring on him a month or two before they cancel his run that he needs to end it - hardly his fault.
I know you liked it because it had action that modern comics lack,
It had truly great action scenes, cool moments*, actual heroism pitting Thor 'against the odds', interesting new villains and decent pacing.
*so good in fact Aaron copied one scene from Jurgen's Mangog fight in his current debacle of a run
...and inarguably Gorr is somewhat like Desak.
...and Jurgen's also had Thor Girl.
...and Jurgen's had older Thor with one arm.
...and Jurgen's had Thor unworthy to lift Mjolnir.
but books used to have more action in general than modern comics.
- They certainly had BETTER action and better consistency.
- I'd argue a faster turnover of stories leads to more conflict (and thus more frequent action) than decompressed stories. Decompressed stories (such as the typical 1 story in 6 issue formula we see today) devalue the worth of individual issues. They might well read fine in Trade format but they are generally weak as individual issues.
It's "good" by comparison, not on its own merits.
Jurgen's run, certainly the 50+ issues preceding the Reigning were fantastic and conceived to be a new readers introduction to Thor who had been off the shelves for several years.
Jurgen's was basically Defalco with better ideas, but worse execution.
In my opinion its one of the best runs and probably THE best jumping on point for new readers.
