Everyone talks about how kids just aren't into toys anymore...

I think more than half of it has to do with price. Most toylines are currently priced out of the spur of the moment "Mommy mommy I need this!" "Well, okay, sweetie." price range.
Look at the lines that are still doing good... My Little Pony (which typically costs $5-$8 per doll), and TMNT, which is $8 for a pretty decent figure.
Both lines are really good values for what you get. And most importantly, they're priced where they don't hurt the wallet so badly.
As was said, in five years time, MU, and a simular DC scaled line will probably be $15.
Toys are just being priced out of the market.
