He-Man and the MotU: The Complete Series (2009)
39 episodes split over 4 discs (26 in S1 + 13 in S2).
Wisely taking into account how badly The New Adventures of He-Man (1990) was received, Mattel tried a second MotU reboot in 2002 with designs that were less of a departure from the original 1983-85 series. Characters and locations were updated but remained instantly recognisable.
The opening title sequence sets the tone perfectly; it references the old series and then cleverly and effortlessly lets you know in no uncertain terms that this version of MotU is new.
The rebuilding of the franchise is mirrored in the gradual rebuilding of King Randor's Kingdom. The threat of Skeletor necessitates that it be fortified and that loyal subjects are recruited to defend it, meaning the core team members return.
