I'm on the side that liked Littlefinger's death scene, overall...but like the above poster, slightly disappointed with some aspects of the show after episode four. Really just the one thing, and that's the show's sudden toothlessness. A few years ago in Season 5 this was the most ruthless show on television. The threat of that ruthlessness made episodes like "Battle of the Bastards" a year later as terrifying and nail biting as they were, and it was still working for episode 4 of this season, which left me breathing like I had just sprinted a couple of miles if I remember correctly.
But after the umpteenth "last minute rescue" scene things are starting to feel a little cheesy and not as suspenseful. Like how many times did the show build up a character's death this season only to back away? Yara in Ep. 2, Bronn in 4, Jaime (twice! in 4 and 7), Tormund and Beric twice (6 and 7), everyone else who went north of the wall in 6 (Jorah twice in one episode), Tyrion in 7, Sansa in Ep. 6, Arya in Ep. 7, Drogon the Dragon in Ep. 4...am I forgetting anyone? Not counting they were definitely trying to fake-foreshadow a Grey Worm death with his sex scene. Don't they need to thin the herd a little?
It might seem like a weird complaint to say, "I want this show to hurt me more," but there you go.
But it ties into the overall problem of the show not being as surprising as it was in seasons past. To be fair, there were lots of little surprises this season, but no big ones.
With 6 (possibly feature-length) episodes to go, I'm still hoping for another Red Wedding...sick bastard that I am.
