Interesting that Season 5 has such an off-model illustration of the show's core character on it.
No buy for me. I have The First 100 Episodes, so even though the volume split bugged me, I have seasons 1-5 already in one set.
I may buy Season 6 though, so then I have complete Seasons 1-5, 6 & 7 and any future releases in one place, and the classic box sets (1, 2, 3, 4v1, 4v2, 5v1, 5v2, 6v1, 6v2) in another.
I would re-buy each and every season if they were released as blu-ray though. Get on that, Nickelodeon. This artwork series works and all.
I'd kill for The First 100 Episodes on bluray though.
