Fair play for listening again - not sure why you're getting stick for posting about, er, music on a music forum, but there you go.
I find the time signature changes can elevate their song but if they annoy you in general it's obviously going to be hard to get past. I think the drummer Brian whatshisname always finds interesting melodies to go with Matt's drawl.
This Is The Last Time is brilliant on every level - think you've been v harsh there. I'm pretty sure he's supposed to sound bored. The lyrics are about being dragged back into a relationship he seems to know is a bad idea. The "woah-oh-ohhs" in each verse are deliberately subdued, they're almost ironic, then there's "I won't be vacant anymore" in the bridge. It wouldn't be the first time he's sung in character.
Hard to Find is a great closer for me. Really love the lyrics ("I don't know why we had to lose, the ones who took so little space" - not even sure how to read that line but it resonates with me somehow).
Tbh it seems like the time signature changes and weaker earlier tracks have maybe annoyed you enough to cloud your judgment on a few later tracks? Obviously it's all subjective and anyone's allowed to not like an album, but there's some songs here that I struggle to see how you couldn't like if you're into The National's usual formula.
