You can google how much the messed up the show if you're interested, there's countless videos and articles out there. But the short of it is that they had the full backing of HBO where pretty much everyone around the two showrunners and head writers were top notch, from costuming to acting to directors. And they were able to follow the first 3 books pretty close to the source material, mostly using book dialogue and with a lot of writing assistance from the novel series author, GRRM. The success went to their heads and they refused to listen to anyone's heads but their own, and GRRM never finished the last two books so they ran out of source material to adapt starting around s5. As they started deviating from source material even as early as s2 and 3, the show got proggressively worse. Generally scenes based closely to the source material was top tier, and scenes or plotlines that deviated or went ahead of the published material had mediocre or crappy writing. The last two seasons were some awful writing with terrible implications (i.e. a girl saying her sexual assaulters made her strong), and the final season is pretty universally hailed as awful, by the main actors as well. The effects were always pretty, but their decisions for plot and dialogue revealed them as hacks.
Wow that wasn't very short, sorry I did that to you.

I mean, when they were working off source material they kind of did a great job.
