These DVDs are a great nostalgia trip generally.
The inclusion of the five-part storyline, Thundercats Ho!, is much appreciated (though as it was also released as a film, the choice to watch as one integrated story would probably have worked better on the DVDs than watching the intro/outro sequences and flashbacks to last episode). The defeat of Mumm-Ra, the main antagonist, in the previous series leading to Lion-O's accession to being "Lord of the Thundercats" however seemed to mark the start of decline.
Mumm-Ra's ingenious return in this series is a great plot twist, but with successive defeats and reincarnations, Mumm-Ra starts to look particularly weak and the accompaniment of "Ma-mutt", the counterpart to Lion-O's Snarf, unfortunately leans towards a parallel of Dick Dastardly and Muttley.
To bolster this, there is the inclusion of a new faction, the so-called "Lunataks of Plun-Daar", who even make the former Mutants cower from shadowy rumour of their name. However once they appear, their mystique crumbles in the face of a rather punk-based group of misfits. The most interesting of these enemies is not their leader, diminuitive "Luna" on her henchmen/steed, but actually their psychic/hypnotic trooper "Alluro". His voice seems to be a contemporary of Eddie Izzard, but his talents simply extend to instilling despair and hopelessness, leading to his mantra "Let's face it, You don't stand a chance!!". Its unintentionally funny, especially as a climax before the unsuspecting Thundercat is rescued by the cavalry.
Similarly "Chilla" who is a glamourous Ice Witch (who can strangely also restore heat) is an underused character compared to the others in this group. The flying fortress however is a good concept. The Mutants however are predominantly sidelined to being manipulated by either the Lunataks or Mumm-Ra into being involved with their schemes.
Beyond that however, the actual Thundercats themselves progress with the expansion of their territories and new players of Pummyra, Ben-Gali and Lynx-O and much use is made of the blind Lynx-O and his Braille-board to overcome the blindness he suffered in the original Exodus episode. Although his prescence is laboured, Lynx-O as a character often manages to demonstrate that his blindness impairs him only physically, as his other senses greatly compensate and also manages to exploit the prejudice of various captors who believe he is weak from being unable to see.
In spite of my criticisms, it is an enjoyable series and generally my adult scrutiny will be the factors most children will ignore, as it is the continuing conquest of the heroes against seemingly impossible odds that is the draw. Parents will also generally appreciate the cartoon violence is present but minimal and involves Star Wars style sword and space battles and karate action as well the moral-driven plotlines, being generally a variant on wariness towards overly charming strangers.
Overall a good addition to cartoon collections, both new and old.
