Well, we had a suckerpunch thread, so...
Thought the Starks and Lanisters were good.
Baratheorn (spell?) didnt seem so much like an aging warrior king to me. Seemed too soft and good-humored. But I guess Brian Blessed has ruined that role for everyone.
The Targaryen we're totally harry potter!! - like Draco Malfoy and Luna Lovegood exactly! My suspension of disbelief went BARP-FAIL! when they were onscreen.
I also thought the Dothraki were too 'pretend barbarian', like dressed in designer rags with faux-dirt smudges on them, as if they were off to a costume party. Or maybe it was that they had the type of unnatural musculature that you can only get from gym work. both. D.d. Laurentus can get away with Arnie in a campy fantasy, but it looked out of place here.
I enjoyed it a lot, but the Targaryen/Dothraki scenes were not up to scratch.
