Perhaps it was due to the several years (I've heard anywhere between 6-15) in production but the animation is well behind the times, worse than films made 10 or 15 years ago. It makes Betty Boop cartoons look ground-breaking. It would be barely be a passable video game. If only the animators had opted for hand drawing style featured in the final credits.
There are two things that make Delgo of note, however. One - how they ever managed to get such a long list of notable voice actors is a miracle. The cast includes Freddie Prinze, Jr., Jennifer Love Hewitt, Anne Bancroft, Chris Kattan, Val Kilmer, Malcolm McDowell, Louis Gossett, Jr., Michael Clarke Duncan, Eric Idle, Kelly Ripa, and Burt Reynolds. I wonder how many of them even got the entire script, or saw a frame of the finished animation.
Secondly, Delgo has the distinction of being the worst-performing wide release ever. Opening in 2160 screens, is barely broke half a million dollars. Since the next-worst opening record was $2 mil, they should have this record in the bag for a long, long time.
