Other than TMNT and the Spectacular Spider-Man (which is dang good, lemme tell you) and Tom and Jerry tales, there's nothing worth watching period. Of course, you could tell the end was near with Kid's WB when they had crap like "Skunk Fu" on the line up. Seriously... Dreamwork's Kung Fu Panda is bad enough (I had the desire to see it, but lost it months ago). Stop milking the kung fu parody genre till the parodies outnumber the originals. You did that with Superheroes, and they haven't been great since The tick and Freakazoid left the air.
I think you could tell Warners wanted out of cartoons all together. Loonatics Unleashed? That was a cry for help, if ever I heard one. Though they did have sort of a good idea in season 2. Super Hero versions of the Looney Tunes fighting supervillain versions of the bad guys. But the damage had been done, and any potential for a funny Looney Tunes superhero show were shot to heck. And for some stupid reason, Duck Dodgers, a fabulous cartoon, was tossed aside, like it never existed.
Coconut Fred was their lowest stunt ever, though. Nothing but a total knockoff of Spongebob. That was a nightmare.
