The first half of the game is definitely better than the second half, there’s no doubt about that. And the area you’ve got left before the final encounter isn’t going to make you feel any warmer to it as it’s a pile of arse. The last boss and the DLC are pretty special though.
It’s a game that grows in stature when you’re not playing it as much as when you are I think. People forget the bullshit moments in DS1 when eulogizing it because the peaks are so very high. I know I do. I doubt you’ll ever learn to love the Tomb of the Giants but you might find yourself feeling oddly warmer towards it when you’ve got some distance between being savaged by those weird massive skeletal dog beast bastards in the dark.
I highly recommend watching some lore videos when you’re done (I’ll probably spam some at you) so you can join us in appreciating how clever it all is and cement yourself as a proper Dark Souls wanker.
