Season 7 was a letdown for me. I became accustomed to the unpredictability, which has disappeared the moment they ran out of source material. Now it feels more like a high budget Hollywood flick, where none of its major characters are in any real danger,where everything is fan fiction and where you get the feeling everything happens and is shot purely to make merchandise from it.
(For example The fake tension at the frozen lake, where you get sad music, a shot of how defeated they are, followed with a faceshot of every character, so people would think they're in trouble, just to be saved a la deus ex machina- The way it was shot, I couldn't stop thinking of marvel's avengers)
Overall I liked some of the reunions, it had some great visual effects and beautiful scenery, but as I said, the excitement is gone; it has become yet another predictable television show that doesn't dare to make major leaps.
Negative:
Tormund should have died in the 'true north', The Littlefinger plot was a real disappointment, The fasttraveling made me motion sick, The whole capturing a whight to convince Cersei was horrible. Some scenes were just there to mislead the audience (E.g. Arya and Sansa). I literally cringed during the last 2 episodes
Positive:
The Visuals and CGI was good. Performances by most of the actors (especially the Lannister cast) was on point as usual. There were some satisfying reunions and interactions.
Overall it's worth watching, but don't expect it to be the same as previous seasons.
