FYI, Darth, Krang made a gag cameo in an episode of the current TMNT cartoon, and in another episode, Gen (a rhino from Usagi Yojimbo) dressed up like Rocksteady and chased after a pig-type guy who looked like Bebop. I think I'm good for Fred Wolf TMNT characters in the 4Kids series. Be interesting if they tried to work Irma into the series, though.
Batman had been a major character in comics for over a quarter of a century befor the Adam West series. The Adam West series didn't make Batsy a super-star in quite the same way the Fred Wolf series made the TMNT big names.
Actually, on I believe the first B:TAS single DVD, Timm said he wanted the show to have elements of the West series (as well as elements of other incarnations of the Dark Knight), but still being distinctly different from the West series and other Batman incarnations. And Tim Burton admits to loving the Adam West series.
Seems a bit cruel to treat it as the black sheep as the franchise, especially when there's TMNT-related stuff like this:

Speaking of Next Mutation, I bet Laird doesn't hate the old cartoon half as much as he hates a certain female turtle (As the 2K3 show has quite a few obvious nods to the old show, whereas Kevin Munroe said Peter would even let Venus be so much as joked about in the recent movie).
As, for what I feel the direction of the current show should be? Well, can't keep adapting existing issues, storylines and characters from existing Mirage TMNT comics?
