I'm sure we've had a dozen topics like this before in the past of what would you do/change yada, yada...but I figured for a show that's over 12 years old now I'm sure there are some things we would like to change or at least expand on if ever the opportunity arose.
For one, the humor was a major weak spot of the show when it tried to balance out the dark elements. The characters Antoine and Dulcy were usually there to try to lighten the mood and provide some chuckles, but I find that most often they missed the mark and came off more as minor nuisances. If you look at Antoine's character, he is obviously based off the famous Inspector Clouseau of the Pink Panther films. A complete moron with an outrageous bad french accent who tends to walk face first into danger. Instead of Antoine being the third wheel of most missions, I'd have made him more of a wild card. A guy who screws up in hilarious and unexpected ways that will not only get the Freedom Fighters in trouble, but then make things worse for Robotnik than they ever could. Could think of some great ideas with this formula if done properly.
Another thing I felt could had been expanded upon, was the character development. Now, for only having two seasons I found it did a good job with what it had. It centered on Sally and how she felt, some of Bunnie, and Sonic's plight with his uncle. But I found when it came to Robotnik, he had no story. He was just always evil, and always plotting. What we saw in the Blast to the Past episodes isn't really an origin so much as a prelude. Same with Snively.
Anyway, I wanna hear what you guys have to say.
