All Dogs Go To Heaven is considered by some as a classic Don Bluth film, although it didn't do well with critics and some parents due to its dark moments and adult themes like gambling and murder. All Dogs 2, which was made without Don Bluth's involvement, and attempted to be less dark and more like a Disney film. This series takes place after All Dogs 2, and while it's good to see more adventures with Charlie and Itchy, it has some problems.
Basically, the main problem with this series is its continuity. In All Dogs 2, it ended with Charlie being granted a new life while Itchy stays in heaven and living happily ever with Sasha as the pets of David, the boy who serves as the movie's Anne-Marie. The series, while supposed to be set after the film, shows it was obviously made by a different team in MGM that either never watched the second film or decided to do it their own way, as they basically have it where Charlie is still a guardian angel paired with Itchy and he and Sasha never dated. Immediately, this show's setting becomes one big continuity error undoing the happy ending Charlie got in All Dogs 2 in order to keep him and Itchy the focus, which is what angered a lot of fans of the two films to the point where they even went as far as to declare the series as non-canon.
Also, the series is mediocre at best, with some good episodes (like Annabelle, the angel dog who gives Charlie and Itchy missions, taking Itchy's place when the two have a falling out), and even introducing some characters (like Belladonna, a demon dog who is actually Annabelle's cosuin, even going as far as to have the two share the same voice actress), the series is basically mediocre at best, as most of the episodes are Charlie being a jerk and doing stupid things to get his way, only to learn a lesson afterwards, something a lot of cartoons of the time have done (with some doing a better job at it). If you are a fan of first movie, second film, or both, I recommend ignoring this or treating the series as its own universe, as the continuity error-plagued plot, mediocre episodes, and the fact it replaces most of the voice cast keeps this from being as good as the movies it was based on.
