Well, the CG TMNT (2012) TV series had its series/season 5 finale and I finally watched it today. It was a cross over episode with the original cartoon and all the voice actors reprised their roles (save for shredder with James Avery who passed) and there was tons of references and it was awesome, the end of the CG series is actually in the original cartoon dimension with the old animation and everything so thats really awesome. The bits from the original cartoon animation are with the art style from the original opening/season 1 (the animation and look changed a bit while the show went on and it almost looks like an anime in season 1 and the opening always had incredible animation). There was also a part where they intentionally had the wrong turtles voice actor which was common in the original cartoon to see the turtles exchanging a voice actor here and there (that moment when mikeys voice was over leos character, jeez).
Anyway, I just cant say enough about how awesome this TV series was. It is definitely the second best TMNT show after the original of course, they did an excellent job with it and it ended well and it wasnt abrupt (the turtles are literally talking about how NY is finally safe and there isnt anything to do in the first parts of this episode). Season 1-3 are really strong, and especially season 1 getting to watch the turtles evolve in this show is well done, plus all the references just keep us old fans coming and as a fan that has been watching it since 2012 I fondly wish the show adieu and it had a great run that I thoroughly enjoyed watching, wish there was more and it didnt end I am definitely sad to see it go I could totally watch more.
