Teenage Mutant Ninja Turtles was a series & toy that became super huge in the later 80's. It continued into the 90's with much success! Originally airing on Fox, and later on CBS. The later seasons (including 9) had some differences from the earlier seasons. The turtles would face a different wave of bad guys. Dregg is the new main bad guy. He is backed up by alien/robot characters. They meet a character named Carter. He also has studied martial arts. April has a different outfit. And doesn't really work for channel 6 news. And what's majorly different is the turtles mutate into bigger weird looking turtles! Carter also mutates into a big Native American warrior looking dude. The animation is different as a whole too! In my opinion, it isn't for the better. The animation isn't horrific. But it's a step back from the orignial earlier animation. I remember watching these episodes on CBS. They we're pretty cool still. However I found the earlier seasons more enjoyable in most aspects. The series also seems to take on a more serious form to it. Not quiet as many jokes. Like I said...It's still pretty cool. But people that grew up with the turtles when they started the series, probably agree the older seasons are slightly better. I definitely recommend this DVD/season to anyone that was into the old G1 TMNT series. And even the kids of today should enjoy it. My 9yr old son loves TMNT. He has the 2003 series on DVD. And we have almost all the original series. He favors the old series. And he does enjoy this DVD along w/ all the other old schools. This DVD has 8 episodes and is the entire 9th season.
