Superior mix of muppetry and traditional animation. I'm only familiar with Dog City from the four episodes available on VHS, but these were enough to make me wish someone had released the whole series on tape. The characters are good, the dialog often sophisticated and should appeal to adults as well as kids (especially adults with an interest in the animation industry. The scenes where Ace Heart (the main animated character) converses from his storyboard with Elliot (the main muppet character, his animator) are great. Ditto the way events oin the animator's 'real world' seque into plot arcs in the animation series-within-a-series. Very clever and appealing all round.
I'm not a huge muppet/Henson fan, but this one was cool. Shame it never got the recognition it deserved.
8 out of 10 for an animated TV series.
