This is not a fast-paced, action-oriented show: it's slow and deliberate, meditative. The first five episodes particularly explore the setting of the town of Glie as well as some lore about the Haibane themselves and their roles within the society. After that, the show becomes much more emotional and places a stronger emphasis on the characters' psyches. Everything shown connects and leads up to an exceptionally beautiful and profound conclusion.
Haibane Renmei is akin to snuggling under a warm blanket with a hot cup of tea on a rainy day, it's a balm for the soul and it's immensely comforting. The show is wholly satisfying and beautiful from the beginning to the end; if you're someone who enjoys thoughtful media and taking the time to reflect on yourself and the world around you, you'll like it very much.
