I don't really have anything big to say about this OVA. Like other manga pack-in episodes, its really just like an extra episode of the original series. In terms of quality its pretty much on-par with the original, although it does surpass it in a few areas. I personally found this one a bit funnier than some of the original episodes, but that could just be me. It still has the cultural references that the original had, but I think this episode had less than the ones in the original season (unless there are like 50 I just couldn't tell were referencing anything). Overall, ifyou watched and liked the original, I see no reason for you to not watch the OVA, its just a bit of extra Joshiraku.
