Batman and Jonny Quest

Jonny Quest was a pretty cool cartoon for me as a kid. Despite the presence of a cute animal sidekick, they played it pretty straight, which set it apart from most animated programs of the time. I haven't seen an episode in years, I wonder how well they hold up. I am surprised that we haven't seen a big screen adaptation of this property yet. I have read of rumors here and there over the years, so I assume it is only a matter of time.
