White Album 2, for me, is very good. Each aspect of this anime is done very well. The story is fantastic. It is very believable, and you will get invested to the plot and the characters. Speaking of characters, that for me is another strong point of White Album. Haruki, Kazusa, and Setsuna are all very likable, and you could easily emphatize with all 3. They are all three dimensional, with motivations, goals, and flaws. Another strength of this anime is the sound. Though the BGM doesn't exactly stand out, the music that the characters perform are actually very good, and you would fall in love with 'White Album' by episode 1.
If I have to state any weaknesses to this show, it would have to be the animation. Stills appear numerous times. The one that particularly irks me is the concert one, where instead of showing us, say, the atmosphere within the gymnasium, or the audience just rocking out to the music, we get a montage recycled animation from the last episodes. A bit lazy there, I think. It didn't actually affect my experience much, though, since I'm more of a story guy than an art guy.
I hope you could see where I'm coming from when I gave this anime an initial 10. So why did I take it back? Well, in my personal opinion, there isn't what I'd call an 'x-factor' to it. Even though White Album 2 is great in pretty much all aspects, there's really nothing that stands out from it. I noticed that those animes that are 10-worthy really has aspects that make it stand out from the usual crowd, i.e. Steins;Gate with its stellar storytelling and character development, or Clannad A.S. with its heart wrenching scenes.
But for what it is, White Album 2 is a really damn good romance. It's very well made, and I highly recommend that you pick it up if you have the time.
(Note that this is my first review, so apologies.)
