Yeah I mean, after the nosedive the writing took from S4 to S5 (4 was the best season overall IMO, 5 the worst), I found S6 and S7 to be fine. It's definitely not as solid as seasons 1-4, especially in terms of dialogue and writing, but there are still some great moments (and a few brilliant ones), and the spectacle is unmatched. Probably more than anything, S6 and S7 are better simply for marking the point of FINALLY seeing this story move into the endgame territory, particularly if you're a fan of the books from before the show started.
I've also been invested in these characters for so long that the well-done cathartic and/or heartfelt moments play me like a fiddle. Even the less amazing actors on the show work for me at this point, it's a bit like Star Wars. Like, Emilia Clarke and Kit Harrington don't always knock it out of the park, but they've just "become" Danaerys and Jon Snow for me at this point (same is true of many other characters).
I've mentioned it before but no episode of television or even cinema has ever hit me as hard as Battle of the Bastards. The combo of my still-genuine investment in the Starks and wanting to see them finally reunite and kick some ass combined with the catharsis of it actually happening (and in pretty epic fashion) was like nothing else for me. Literally the only other thing that could have drawn such a strong feeling from me was, ironically, Star Wars, but TLJ was a such a letdown that it made me lose interest in the franchise in a way I didn't think was possible.
So yeah, I'm all aboard for the climax of GoT. As long is the writing doesn't get S5 levels of bad, the spectacle and catharsis of seeing this series come to a conclusion will be enough for me.
Mark my words, we will miss this show when it's over. It's far from perfect but good cinematic epic fantasy is incredibly hard to pull off and I doubt we'll see something on this level again for a long time.
