So far they've been crap, of course. When has Tom & Jerry ever been good? It's just hitting each other over the head with skillets and crap.
The new Scooby-Doo show is worse. Leagion of Superheroes is on later, so maybe that will suck less. The dopey new Batman show premieres, too, so I'll see if that's as lame as it was last season.
