Amazon might be combining the reviews for the first box set releases and the newer 12 episode two disc "set", and if so let me make it clear that I am talking about the newest single ammaray case being released on July 12th, 2011, with Lion-O centered on a silver background cover.
A word of warning to those interested in buying this new set - it's exactly the same release as the previous season sets, only with fewer episodes!
IGN.com gave a review that stated:
"This new set runs roughly $15, but there's a serious catch - the original DVD featured 33 episodes of the show. This set contains just 12! Considering there are 65 episodes in this first season and 65 episodes in the second season, this two-disc set is ripping off consumers by charging more and offering less overall. For shame...
You might be wondering, though, is the presentation better, at least? Nope. It's a direct port of the previous set. Strike two...
If you already own ThunderCats on DVD, do not buy this double-dip. It's really just a port of the previous disc with no new material and the same A/V presentation. In fact, I can't even recommend it to newcomers. In the long run you'll spend way more on these sets than if you just broke down and bought the four-volume complete series DVD. Unless these sets wind up in a $5 bin, avoid them."
You can still find the first release sets for sale on Amazon for $20-$25 a piece (volume 2 - Season 1 part 2 - runs considerably high at $44 at the time of this write up though).
