Yeah but there's nothing to say that a non-Cartoon Networky TF series wouldn't be marketable... after all, all other TF series up till now haven't been in this style and they managed to succeed well enough for 23 years. And as my comparisons with X-Men, Batman, Spider-Man etc. illustrated, other franchises have been able to produce series following movie franchises which have been more influenced by them yet still targetted at kids. You can make a line that simultaneously appeals to adults and kids - Beast Wars proved that this was possible. It does require more effort and dedication though.
