I think my three favourite shows at the moment are:
Spartacus (and surpisingly not because of the copious amount of boobs). The fight scenes are extremely well choreographed and the injuries far more realistic (even if some of the SFX on them aren't perfect). I'd love to see the producers of the series do a Conan TV series, I think they'd finally be the ones to do a proper Conan if they did it with the level of violence that Spartacus has, with the proper cleaving of heads like ripe melons Howard so enjoyed.
Game of Thrones. Excellent adaptation of the books so far. A couple of very minor gripes but that is really nit picking.
Walking Dead, again a pretty good adaptation and I think some of the subtle changes from the comic have been necessary for TV.
Also still like True Blood, Fringe and Falling Skies. Along with Castle, Supernatural and Grimm.
