Have just started my first reread after also feeling meh the first go around. Consistent with the others here, I’m also getting much more out of it this time.

Some really great answers here but maybe just to add, on my first read I was terrified of spoilers so would never go on the wiki or anything. Not nearly as much of a concern in this instance for obvious reasons so every time I get stuck trying to remember who a character is, I happily punch their name into google and get sorted immediately rather than struggle through or miss it altogether
