I just marathoned this to the end.

What can I say? It was absolutely awesome. I can't believe they managed to flesh out and use up the extremely large cast. Amazing. This show needs to be watched in one sitting. Too many things happen to too many people to keep track of on a weekly basis, but if you watch it straight, you'll see how intricately woven the story is from dozens of finer plot and character threads. The foreshadowing was excellent, and the climax climactic. Everything got tied up properly, despite how dangerously close it came to dangling everything all over the place. Magical black glue literally pasted everything together at the very end.

Shinra X Celty is the best couple in anime period.

I will avoid spoiling until I see others watch this gem to the end. Trust me, it's worth way more than one weekend of your life.
