Huh. Kinda like it, except the weird whip lasso thing hanging on her hip. The rest is pretty spiffy.

It is all silly and the idea is people are too stupid to seperate the tv show from the movie. Yet they made a horrible Birds of Prey with Batman in it.

After watching the JSA last week, I' actually enjoying this show now, I liked this episode, I liked the end when the kid gives Clark the picture, "I like the S better"  that was great.
