- general weak writing, i havent watched season 8 since it aired but i remember a lot of eyeroll moments
- major characters have their personalities shifted pretty dramatically as you can tell the writers are rushing to get stuff done
- Various major plotlines are completely abandoned (big one i remember
jon snow being a targaryn going nowhere, nothing happening with melisandre, arya not doing anything with the faceless man training that took like a whole season, etc) - the entire show there is this buildup to this big war, and a major plotline for the entire show is ppl trying to get the various warring nations to take this big war seriously. in season 8 the big war finally happens. it's resolved in one episode and basically no major characters died
- the last episode is especially weird, i remember reading the leaks for it and i thought it was a joke because the resolution is so odd
personally i started noticing the cracks in the show around like season 6, but 8 took it to a whole new level. i think the finale might be the worst episode of tv ive ever seen
