Sci-Fi has a review of the first set of Voltron DVDs. Here’s a small part of it:

… there’s an awful lot to like in these opening Voltron episodes, from the slow-burn plot arc to the careful establishment of five iconic characters: Keith (the dashing, blandly perfect leader), Hunk (the big, slowish but good-hearted one), Lance (the “edgy” smartass), Pidge (the brains-over-brawn kid) and Princess Allura (the obligatory girl, and often the team’s weakest link, in emotions and skills alike). These five characters became prototypes, often imitated and often shorthanded, in part because they were established so well here, with episodes focusing on each of them in turn.
