As for season 1: Plot: really liked it, it's structured not as well and deep as the game, but the story was really enjoyable.

Actors & Actress and Acting: well, the cast was not the best one, in my humble opinion. They have not that many facial expression, and that's a shame as this show (game) was mainly psychological, so facial expressions are very important.

Visual Effects: a very good part of the show. I also loved the part were they showed the classic Bloater kill in the background.

Soundtrack: very good, very near the level of the game. Totally loved it.

Conclusion: not at the level of the game (well, maybe because of the fact that the game you actually live it) and it's way different (only the main flow was kept), but in conclusion, as always, HBO didn't deluded. The cast was meh and, as someone else rightfully said, the pace of this show was wrong, too many things were cut out and that's totally a shame.
