Yeah see this is the thing, Angel is about the characters and their journeys. Unless you go through the seasons with the characters, it can't be fully appreciated unfortunately.
I love the one where Cordelia takes Angel's car to go save Gunn, and Angel and Wesley need to go somewhere so they take Wesley's motorbike, but his passenger helmet is pink. Wesley's like, 'what's wrong??' and Angel says, 'Nothing, it's, it's just I don't really need a helmet anyway and WHY DO I HAVE TO WEAR THE LADIES HELMET??' and Wesley goes, 'oh stop being such a w**k*r and put it on!' so he puts it on and you can see his eyes going and Wesley smirks and says, 'looks good. Hop on board, gorgeous.' It's hilarious, you then see Angels eyes again and it's obvious he's laughing to himself, I always like to think that's actually David getting a laugh out of doing the scene
