Its not even close
Game of Thrones is a better show on every possible level.
Superb scenery, costumes, visually GOT is probably the best show ever produced.
WD, the woods in georgia......woopee!
GOT, profound, intense, interesting, well acted ( even the children), multiple plots which are all connected, abundant amount of interesting characters all with histories and back stories.
WD, Lori fucked Shane, Glenn fucked Maggie, Merle is an asshole, Governor is nuts......Oh and dont get bit by a zombie.
Also about 50% of the show is long, drawn out interpersonal scenes that nobody gives a crap about.
Its also just unrealistic. Ok, so the whole world, every person and huge military force in the planet got over run by slow moving zombies?
Game of Thrones beats Walking Lame in every way.
