Bought this a while again as a long time manga reader and anime watcher, and was impressed with the language options. You can watch it in English dub, Japanese or Japanese with English subs. As someone learning Japanese this was a great function. On top of that, once you've selected a language, it stays in that language for all the episodes (I've had series before that swapped back to English for each new episode). The case is a large DVD case (not a cardboard cover over several cases), with 5 discs inside, meaning four episodes per disc. The artwork on the cover looks good, and there is a handy episode guide on the inside of the case (hidden under the first DVD), so you don't have to fiddle through discs for your favourite episode.
I'm sure most people browsing the series will already be familiar with it, but if you're not then it's similar to other popular mangas like naruto, only it's a lot more action focussed. There are some very cool powers in the series (I still read the manga when it comes out online; the series is definitely worth following all the way!). Sometimes I find that (at least in the anime), Bleach can use comedy at the wrong moments, killing the mood a bit, but that's not a problem in the first series, more so a bit later on.
So, whether you're collecting the DVDs of your favourite anime series like me, or this is first introduction to Bleach (or even anime), you'll love the series and be wholly satisfied with the quality of this set.
