I had been curious to watch this series again, since I have very fond memories of the shows from my childhood. The complete boxed set was abruptly discontinued, so I'll be trying to collect all of the volumes and season sets individually.There were only five episodes in the first season, which is sort of a miniseries to introduce the Turtles and establish Shredder as their main enemy. I did watch one of the "bonus" episodes from season 10, but want to wait to view the whole series in order before watching any more. If you buy the season 10 disc, it should duplicate the "bonus" shows from this DVD (plus the portions of season 10 that weren't included here).Without giving away too many spoilers, I noticed recurring themes in the miniseries. One I had kind of missed while growing up - the idea of Master Splinter returning to human form. Raphael felt like a slightly different character. I knew he was a wise guy who liked to joke around and use sarcasm. In these episodes, I saw a more caring side of him, whether he was encouraging his brothers, or expressing concern over Michelangelo getting buried in a pile of rubble.My 5 star rating is mostly based on the content. As some other reviewers have mentioned, the audio and video were probably left as is, rather than being remastered. My setup is a progressive scan DVD player, outputting via component cables to my surround sound receiver. From there, the receiver supposedly upconverts the video to a 720p signal, and I watch the shows on my 32" 768p HDTV. On the couch, I'm probably 8 feet or more away from the screen, so the video looks fine. Episode #2 had some weird "artifacts," where it looked like extra lines were added to the picture (maybe from the deinterlacing process?). The sound isn't overpowering, with a simple two channel stereo format. I had to turn it up a little bit, but voices are clear, and I didn't hear any background noise (unfortunately, some of the other DVDs in this series do have audio issues).What more can I say? If you grew up with the Turtles, this is a good purchase or rental. I'm looking forward to collecting and watching the remaining 188 episodes!
