I first want to make clear that my low rating has to do with the fact that this is just the same 26 episodes you can get on individual dvds or in the Class Album. The Vol. 2 threw me and without any description to go off of, I foolishly hoped that it would somehow cover another awesome year with the Azumanga girls in 26 new episodes. No such luck.
Anyway, if you've got all 6 original dvds or Class Album, you won't find anything new here other than trailers, from what I was able to discover. Just something to think about.

Have finally watched the singles I had vs. the same discs in the box set. Much like the re-release of the omnibus book, it is a slightly different translation. Previously, I'd only watched the 2 discs I didn't have in single version, so I had nothing to compare it to. Still not sure the different translation is worth it, but I'm still glad to have all the discs.
