The Play Stage is the thing, wherein to catch the Spirit Play.
The designers clearly went to a lot of effort to get that used feeling right: the dust clouds when entering rarely used corridors, the damaged doors, that odd bits and pieces in corners that speak of little maintenance.
In any part of Old Home the atmosphere reflects how the Haibane interact with the space, both individually and as a group. The guest room where they gather is a bright, cheery, place that is still shaped by Kuramori’s gentle spirit. Kuu’s bedroom was also a comfortable, happy space, and Rakka’s room would have been heading in that direction.
In contrast, Reki’s suite was a place of loneliness and despair, and was usually lit accordingly.
This careful design of the staging of Haibane Renmei supports the story well and is an aspect that I adore .
The Play question is the thing, wherein to catch the Spirit mind.
Back when I did the Thirty Days of Anime posts I pegged Kyuuketsuki Miyu as the first anime that I bought . One of the defining elements of Miyu is not telling the viewer everything. Such answers as are there must be worked for, and failing that speculated wildly about.
Series with an air of intrigue or mystery, like Miyu, Key the Metal Idol , or RahXephon have a good chance of catching my interest. This aspect hooked me when I first saw Haibane Renmei, and it hooked me again this time around.
I had an absolute ball writing Who Were They Before They Were Haibane, and that is only one of the topics where wild guesses can run free.
The Play flaw is the thing, wherein to catch the Spirit heart.
A mysterious setting, or a story where all the answers are not given, might be enough to catch my interest; it is not enough to keep it.
I have to be able to connect to the characters, to care about them. At one end there is the vague  concept of the Mary Sue who is so perfect that no one can really relate. At the other end there is the set of basket cases and bastards that the viewer either doesn’t care about, or hopes will die horrible bloody deaths .
Haibane Renmei has neither of these problems. Hikari may be a touch generic but that is the biggest issue I have with the characters.
Generally speaking the characters of Haibane Renmei are well balanced characters: nice people with problems or issues that the viewer can relate to. These problems may run a lot deeper for Reki and Rakka but never break my sympathy or hope that they will recover.
Having those hopes realised is what makes the series work.
It is what made me cry when Reki achieves her Day of Flight.
For the most part there is a sense of depth to the other Haibane that make them work well as characters: Nemu’s quiet loyalty to atone for her earlier rejection of Reki, Kana’s sensitivity hidden behind the brash tomboy, and Kuu’s serenity as she accepts her identity all spring to mind.
In Conclusion 
The experience of Haibane Renmei will change between viewings, and a more measured pace is definitely recommended for later viewings. I expected this having experienced the same effect with both Lodoss War and The Vision of Escaflowne.
Haibane Renmei is not always an easy show to watch, but it is a deeply satisfying and rewarding one. It has one of the few perfect endings in anime, and would be worth treasuring for that alone.
The complete package of a rich setting, a sense of mystery, and characters to care deeply about, lift Haibane Renmei to the level of a classic that I will come back to again and again.
