Many reviews I've read of XGM gripe at the fact that it is not consistent with 'A Goofy Movie', which I agree was an excellent movie. But it is clear to me that Extremely Goofy Movie was not made as 'Goofy Movie 2'. The setting is different, characters are new or at least 5 years older...the only thing the movies have in common is the theme of the bond between Max and Goof. And they both explore that in very different ways, focusing on different aspects of the generation gap. And I think XGM is a great movie in and of itself and does not invite comparison, plot-wise, to the original. It is just as good.
It's also nice to finally get a movie that's not made purely to sell toys.
