Just started watching it as just re-started HBO subs. Nowhere near as good as BoB, the fighting scenes are undoubtedly bigger/better/louder but the characters are just plain boring, I didn't find one character interesting, actually fell asleep in couple episodes. Story and characters are tenfold better in BoB. Glad I saw it now as would have very much regretted the blind buy.
Be careful if thinking it's near as good as BoB.
