At ColorBurst, we do a lot of ‘fix my footage.’ The first thing I do is try to understand what makes it “bad footage.”
Improper exposure, color balance, focus/sharpness, noise/grain, vignetting, etc can each make footage look “bad.” We work through each shortcoming to improve the final image, usually starting with exposure and color-balance, then noise reduction, contrast enhancement and so on. Sometimes we have to even out the auto-exposure/auto white balance from scene to scene, or even within a scene.
There are numerous plug-ins that can simplify the job, but almost everything can be done with the tools that come with AE. So far, I have not found any magic button or plugin that painlessly fixes everything automatically.
Of course, you’re never going to get that mixed lighting, 4-stops underexposed, handheld old VHS footage to look like it was shot with a tripod-mounted high-end digital cam on a properly-lit set. But you CAN make bad footage look a lot better.

BTW – If you post some sample footage, or even still frames, I’d be glad to give you specifics on the way I’d approach it.
