In modern comics Thor (and the asguardians) way of speaking really isn't an issue anymore. I'm currently reading a Marvel Essentials Thor volume (basically, its a b&W reprinting of old thor comics) reprinting Stan Lee/Jack Kirby Thor comics, and its definately a challenge to decipher at times. It feels like stan had a dictionary, thesaurus, and the complete works of shakespeare on hand when writting the dialog, which at times goes from just being an annoyance to actually being a chore to read. The stories are quality, and I love Stan Lee (who doesn't?) but you don't know annoying thor dialog until you see his stuff.
