People looking to "improve" Captain Planet are missing the point of the show. The show was MEANT to be cheesy, heavy handed and preachy. They never set out to make a show that could be enjoyed strictly for the quality of the writing or animation (though it did have some nice action FX actually).
If you want a "good" Captain Planet, you might as well just make an entirely new show altogether. But I guess it's fun to speculate how to take an inconsequential show and make it "better".
